Possible causes of connection timeouts?
Hi,
I am having intermitent but far too frequent issues with connection
timeouts on a local tomcat server.
The server is on the local network and 9 times out of 10 the pages are
served up with no issues but now and then the connection is dropped and a
delay of connectionTimeout occurs until the server/client resume
communication. I do not want to drop the value of connectionTimeout too low
as this server will be accessed from around the globe.
What could be causing these timeouts?
Is there a way I can look into what is causing them?
Are there any specific settings I need on Solaris to run Tomcat correctly?
After plenty of googling and searching these lists on MARC I have not found
anything.
The server is running tomcat 6, java 1.6 on solaris 10.
Thanks

Thanks Martin I will look into maven.
Switching to solaris has been a steep learning curve, one more thing wont
hurt :)

Hi Gary-
i noticed you're using ./configure.sh?
the only suggestion I can offer would be to use maven for this effort
http://maven.apache.org
that way version specific anomalies/abnormalities would be addressed by the <version> attribute-specifier an example:
<dependencies>
<dependency>
<groupId>fu</groupId>
<artifactId>bar</artifactId>
<version>1.0</version>
</dependency>
...
//Here are the instructions I see from tcnative.spec which include includedir and define tcnver as 1 and not 1.1.10?

RE: Possible causes of connection timeouts?
Posted by ga...@cummins.com.
It looks like this is an issue with the tomcat native connector. If I
remove it I have no connection issues at all.
Any ideas why the native connector could be causing issues?
I built the connector using
TC native -> 1.1.14
apr -> 1.2.12
OpenSSL -> 0.9.8h 28 May 2008
Java -> 1.6.0_07-b06
./configure --with-apr=/CTT/apr-1.2.12 --with-ssl=/usr/local/ssl
--prefix=/CTT/tomcat6 --with-java-home=/usr/java
I see there is a new version of the TC native so I will experiment with
that and different versions of APR.

One thing I have found is that when I set

i.e different to the connectionTimeout
The delay then becomes 30 seconds and not 20s as it would default to with
just connectionTimeout set to 20000.
I think this means I am seeing issues with new requests for pages/items on

Please respond to Subject
Tomcat Users List RE: Possible causes of connection
<users@tomcat.apa timeouts?
che.org>
what are the values of your server.xml connection timeout parameters?
connectionTimeout
The number of milliseconds this Connector will wait, after accepting a
connection, for the request URI line to be presented. The default value is
60000 (i.e. 60 seconds).
connectionTimeout="60000"
connectionLinger: The number of ms during which the sockets used by this
connector will linger when they are closed..-1 keeps the connection open
until socket read/write operation is complete
connectionLinger="-1"
disableUploadTimeout
Allowed the servlet container to use a different longer connection timeout
while a servlet is being executed. Allows the servlet a longer amount of
time to complete execution or longer time during data upload
disableUploadTimeout="true"
socketBuffer
size of the socket buffer to be used for socket output buffering. -1
disables default is 9000 bytes
socketBuffer="9000"

Martin

Please respond to Subject
Tomcat Users List RE: Possible causes of connection
<users@tomcat.apa timeouts?
che.org>
what are the values of your server.xml connection timeout parameters?
connectionTimeout
The number of milliseconds this Connector will wait, after accepting a
connection, for the request URI line to be presented. The default value is
60000 (i.e. 60 seconds).
connectionTimeout="60000"
connectionLinger: The number of ms during which the sockets used by this
connector will linger when they are closed..-1 keeps the connection open
until socket read/write operation is complete
connectionLinger="-1"
disableUploadTimeout
Allowed the servlet container to use a different longer connection timeout
while a servlet is being executed. Allows the servlet a longer amount of
time to complete execution or longer time during data upload
disableUploadTimeout="true"
socketBuffer
size of the socket buffer to be used for socket output buffering. -1
disables default is 9000 bytes
socketBuffer="9000"
Regards
Martin
