Tomcat connections not closing.
Hello Tomcat users,
We are having difficulty with connections to Tomcat remaining open
after the client hits "stop" in their browser.
This only seems to happen when we have a particular combination of
load balancer hardware in front of the tomcats. We are also running
apache and have not seen the same behavior there, even though the
load balancer hardware and config is the same.
We are using Tomcat 5.5.20 on linux 2.6.9-34.0.1.ELsmp. It is
running standalone. We are using APR in some environments and not
in others, but see the problem in either configuration.
We have captured tcpdumps and see the pattern at the bottom of this
email. It appears that the web application tries to retransmit until
it gets a RST from the client after about 12 minutes. When we finally
get the RST, we get a lot of exceptions (some of them are due to the
fact that our session timeout is shorter than the length of these
requests. I can add them later if they would be useful).
When we do threaddumps of the java process, many threads appear to
be stuck in java.net.SocketOutputStream.socketWrite0
Thread [0x00000fd] exceeded timeout of [180000] millis. Current
execution stack

I have done some research, but I'm not finding a cut and dried answer
to this issue. It seems that the RST behavior of browsers has been
noted before:
http://pages.cpsc.ucalgary.ca/~carey/papers/2005/TCP-Resets.pdf
It seems like the main difference between having the load balancers
or not is the timing of when we get the RST.
Some questions:
Is there anything that can be done on the tomcat side to protect itself?
Why does it not send a FIN back when it gets a FIN from the client?
Why would it be different for Apache?
Thanks,
-Mike Roark
Notes on this output. Our application runs on port 8585. The client
sends
a FIN at packet#33. The web app begins retransmitting at packet#36.

Hi Martin,
We are using version control. That isn't really the issue. The
problem is too much data, not too little.

I would strongly suggest use of Version Control for archiving your
configuration files
server.xml/web.xml and context.xml, catalina.policy, logging.properties,
workers.properties, tomcat-users.xml
In the case of axis you want to archive
axis2.xml/services.xml/modules.xml/services
In the case of struts you want to archive struts-default.xml
struts-portlet-default.xml
In this way you determine at least the version of the configurations
(and
hopefully date-time as well as Login)

Well, yes and no.
Yes, the problem has abated, and possibly been eliminated. However, we
have no idea what change fixed it. We changed nothing in tomcat, but
some changes were made at the network and in the application itself
(regularly scheduled updates). None of the changes were intended to fix
the problem, but it went away anyway.
I don't like it, since I assume the problem could come back at any time.
I still think Tomcat should be able to protect itself from this kind of
behavior, but I haven't had good luck yet with the suggested parameter
tweaks. At this point I'm not continuing to look into it, but just
keeping watch over it...

Filip,
Thanks for the help.
You were right about the default for disableUploadTimeout. I must have
been looking at 5.0 docs before, it looks like the default changed
between 5.0 and 5.5.
So I have now specified all three settings as you have them, and have
had no effect. It seems like the socket remains open for as long as I
feel like waiting. I have a perl script that will make a request and
then not read the response (just sleeps), and another that will open a
socket but not even write a GET line. Same result in both cases.
I said that I could see the reads timeout, but now I'm not even seeing
that. I would expect if I don't send a GET that the connectionTimeout
would definitely apply.

yes, even this should not be the case, since Tomcat will set the default
timeout to 5 minutes.
try to set timeout="60000" as well, this is an undocumented option, but
turns into effect when disableUploadTimeout="false"
you're total settings should be,
disableUploadTimeout="false"
connectionTimeout="60000"
timeout="60000"
the last timeout, should apply to your write timeout.

if you are using defaults, then you are not using the correct settings,

yes, even this should not be the case, since Tomcat will set the default
timeout to 5 minutes.
try to set timeout="60000" as well, this is an undocumented option, but
turns into effect when disableUploadTimeout="false"
you're total settings should be,
disableUploadTimeout="false"
connectionTimeout="60000"
timeout="60000"
the last timeout, should apply to your write timeout.

I did try this, but it didn't have an effect.
I did notice that reads would timeout, but not writes.
We were already using the default value of 60000 (60 secs), but our
problem is around the 15 minute mark (of writing).

Thanks Filip.
We believe that disableUploadTimeout is defaulting to false in our
setup.
connectionTimeout seems to refer to the time until the request URI is
received. We are receiving the URI, the problem occurs when writing the
output to the client.
We will give these recommendations a shot though, just to make sure.

RE: Tomcat connections not closing.
Posted by "Roark, Mike" <MR...@orbitz.com>.
Thank Rainer. That's a good point about the sequence numbers.

Subject: Re: Tomcat connections not closing.
Some comments, but not a real solution:
The FIN from the client comes in, when the server had already sent out a
couple of packets without getting an ACK. The ACK in the FIN does not
ACK the latest server packet, instead it is related to a packet some
steps earlier (you can check the sequence numbers). The TCP
retransmissions in you dump are not for the latest server packet,
instead they are for the first packet after the sequence number
acknowledged by the client in the FIN packet. This server packet was
already out in the TCP stack, before the FIN came in.
So I assume the retransmits are done by the TCP stack itself (and those
usually take minutes).
I would have expected the remote side to reply with a RST much sooner.
Usually, if a FIN from the client doesn't get handled by the server and
the client application is not willing to receive further data, it will
RST pretty soon after the FIN. Could be, that you LB or some proxy or
reverse proxy in between the server and the client makes the situation
this bad.
No help, just an ugly workaround, in case Filip's hint doesn' work:
If Apache doesn't have the problem, you could try to put Apache
httpd/mod_jk (or mod_proxy_ajp) in front of Tomcat. If we assume, that
httpd will realize the situation faster, even when combined with the
forwarding module, it will immediately shut the connection to Tomcat.
Between Apache and Tomcat we should not see such a FIN/RST/Retransmit
situation.

Rainer

Re: Tomcat connections not closing.
Posted by Rainer Jung <ra...@kippdata.de>.
Some comments, but not a real solution:
The FIN from the client comes in, when the server had already sent out a
couple of packets without getting an ACK. The ACK in the FIN does not
ACK the latest server packet, instead it is related to a packet some
steps earlier (you can check the sequence numbers). The TCP
retransmissions in you dump are not for the latest server packet,
instead they are for the first packet after the sequence number
acknowledged by the client in the FIN packet. This server packet was
already out in the TCP stack, before the FIN came in.
So I assume the retransmits are done by the TCP stack itself (and those
usually take minutes).
I would have expected the remote side to reply with a RST much sooner.
Usually, if a FIN from the client doesn't get handled by the server and
the client application is not willing to receive further data, it will
RST pretty soon after the FIN. Could be, that you LB or some proxy or
reverse proxy in between the server and the client makes the situation
this bad.
No help, just an ugly workaround, in case Filip's hint doesn' work:
If Apache doesn't have the problem, you could try to put Apache
httpd/mod_jk (or mod_proxy_ajp) in front of Tomcat. If we assume, that
httpd will realize the situation faster, even when combined with the
forwarding module, it will immediately shut the connection to Tomcat.
Between Apache and Tomcat we should not see such a FIN/RST/Retransmit
situation.

Re: Tomcat connections not closing.
Posted by Filip Hanik - Dev Lists <de...@hanik.com>.
connectionTimeout - gets set to your sockets SO_TIMEOUT, but
disableUploadTimeout="true" unsets the value in the line above, causing socketWrite0 to not have a timeout, hence if you set disableUploadTimeout="false", then you will make sure that socket read and writes from your servlets/jsps, will be subject to timeout as well, and not hang.
in your apache httpd conf file, make sure your mod_proxy has a timeout configured as well
after that, I would put in a network sniffer (like ethereal) between apache and tomcat, so that you can see where it gets stuck and why.

Re: Tomcat connections not closing.
Posted by rgoers <rg...@apache.org>.
FWIW we have been experiencing this problem intermittently for 2 years and
still haven't figured out what is causing it. We changed from IBM JDK 1.4.2
to Sun 1.5, tomcat to JBoss 4.0.3. The only difference is that in our case
once the thread gets "stuck" it never seems to time out - at least as far as
we can tell. In our case we might go for a week before we see this happen.
In our case all of the requests go through an Apache Proxy. The requests
might then go through a load balancer - we've tried it both ways - before
hittlng the servlet container.
I'd appreciate more details in why connectionTimeout and
disableUploadTimeout might have some effect - their descriptions don't seem
to apply to this scenario.

Hello Tomcat users,
We are having difficulty with connections to Tomcat remaining open
after the client hits "stop" in their browser.
This only seems to happen when we have a particular combination of
load balancer hardware in front of the tomcats. We are also running
apache and have not seen the same behavior there, even though the
load balancer hardware and config is the same.
We are using Tomcat 5.5.20 on linux 2.6.9-34.0.1.ELsmp. It is
running standalone. We are using APR in some environments and not
in others, but see the problem in either configuration.
We have captured tcpdumps and see the pattern at the bottom of this
email. It appears that the web application tries to retransmit until
it gets a RST from the client after about 12 minutes. When we finally
get the RST, we get a lot of exceptions (some of them are due to the
fact that our session timeout is shorter than the length of these
requests. I can add them later if they would be useful).
When we do threaddumps of the java process, many threads appear to
be stuck in java.net.SocketOutputStream.socketWrite0
Thread [0x00000fd] exceeded timeout of [180000] millis. Current
execution stack
