problems with connector
Hi all,
I'm having some problems with the mod_jk connector.
In mod_jk logs file I have a lot of lines like
[Fri Nov 17 23:07:18 2006] [12236:7072] [error]
jk_child_init::mod_jk.c (2406): Attachning
shm:/etc/apache2/logs/jk-runtime-status errno=2
and from time to time the connector completely locks apache, forcing
me to restart both apache and tomcat.
Any idea? I could find no documentation about this error :((
I'm using debian3.1, jdk1.5.0_05 and tomcat 5.20.
Thanks in advance!!
Enrico

Hi Enrico,
it looks like the config you sent doesn't fit to your problem. The only
configured forwarding rule with JkMount is a comment, so mod_jk should
never try to reach any tomcat. I assume, you added the comment sign when
trying to find the reason to your problem, but this makes me question
the rest of the config, e.g. the connection_pool_size comment.
Before we try to solve your problem: the following lines in your
workers.properties are obsolete, or not used in your situation. You
should remove them:
> workers.tomcat_home=/tomcat/dir
> workers.java_home=/opt/jdk
> ps=/
> worker.ajp12.port=8007
> worker.ajp12.host=localhost
> worker.ajp12.type=ajp12
> worker.ajp12.lbfactor=1
> #worker.ajp13.connection_pool_size
> worker.loadbalancer.type=lb
> worker.loadbalancer.balance_workers=ajp12, ajp13
> worker.inprocess.type=jni
Now to your problem: Please add
worker.ajp13.socket_timeout=0
to your workers.properties and try again. If you can easily reproduce
the problem, it would be nice to increase JkLogLevel to trace (will
produce lots of logging) and attach the JkLogFile.
Regards,
Rainer

Hi;
just to give my 2-cents as a mod_jk user,
i had a similar problem where mod_jk and tomcat was working ok, and apache
was also working ok, but sending blank pages to the user.
noticed the mod_jk log had grown to over 3GB in size, then deleted and
restarted services and started working fine. later implemented a method to
rotate mod_jk log at 200MB.

Hi Rainer
a very big thanks for your help, and also for your work in the
connector project.
My work and passion depends on your work: I will never thank enough
you and the many people working on opensource projects like tomcat.
I will test the new version as soon as it's released.
Best regards
Enrico

Hi Enrico,
I think we will have fixed your original problem, and also the
sendfull/another log lines in 1.2.20. They don't mean anything bad, so
please ignore them for the moment. Watch the list, we will have a 1.2.20
release ready for testing next week.
Concerning the client write error, this usually neans, that the response
of a request could not be sent successfully to the client. Typically the
client is a browser and most often the source of the problem is a
request that runs for a longer time, than exected by the user. So the
user presses "Again" or clicks on another link. The browser then closes
the current connection and starts a new one. Trying to send back
addinitional response packets for the first request then detects the
closed connection and throws an info message. If this explanation fits
into what you are experiencing, then you can ignore these messages two.
They won't go away in 1.2.20, because it is important to know, if this
happens only rarely, or very often. In the apache access log you can log
the response times with %D so you can get an idea, if most occurences
relate to long running requests.
Regards,
Rainer

Only in log files. No visible problems. But every couple of weeks
(about, not always) the connector completely hangs apache.

I added it.
Now the errors are:
[Sat Nov 18 22:43:13 2006] [28124:7072] [error]
ajp_connection_tcp_send_message::jk_ajp_common.c (914): sendfull

I attach the mod_ik logs, with trace enabled, the second with trace enabled.
Thanks again!!!

Re: problems with connector
Posted by Rainer Jung <ra...@kippdata.de>.
Adding to my own comments: I think I found a problem. So one more question:
Do you also observe a real problem, or only the info log messages. Do
the requests actually fail?
Regards,
Rainer

Thanks Rainer for your reply!
Here's my mod_jk.conf
I solved my previous error adding the directive
JkShmFile /var/log/apache2/mod_jk.shm
(see later the copy of the file)
Now I have different errors:
[Sat Nov 18 09:27:57 2006] [16854:7072] [info]
ajp_send_request::jk_ajp_common.c (1170): (ajp13) socket 33 is not

ajp_send_request::jk_ajp_common.c (1194): (ajp13) error sending
request. Will try another pooled connection

ajp_service::jk_ajp_common.c (1867): (ajp13) sending request to tomcat
failed, recoverable operation attempt=1
What do they mean?
I'm using versions
mod_jk/1.2.19
Apache/2.0.54
tomcat/5.5.20
Thanks again!!

Re: problems with connector
Posted by Rainer Jung <ra...@kippdata.de>.
Please give details on your mod_jk version and concerning your
configuration (mod_jk config inside httpd.conf and workers.properties).
Errno 2 looks line not such file or directory. So does
/etc/apache2/logs/jk-runtime-status exist as a file and is the apache
user allowed to write into it. Does the directory /etc/apache2/logs
exist and again, does the apache user have write permissions there?
Does the log message already show, when you are starting? If yes, could
you reproduce with JkLogLevel trace and provide the resulting file?
Regards,
Rainer
