Re: [OT] mod_jk configuration for production
I've read the documentation and my question is :
- socket_timeout = 2s but reply_timeout is 0 meaning that the webserver is
waiting forever. Which of them is used for timeout ajp connection?

Hello,
I am facing to a problem concerning apache-tomcat configuration via mod_jk
for our production environment. We are using Apache: 2.0.55, Tomcat 5.0,
mod_jk 1.2.15.
Our first problem has been raised some weeks ago when the clients received
http 404 errors.
mod_jk logs have shown errors such as:
[Tue Feb 13 08:36:03 2007][info] ajp_send_request::jk_ajp_common.c
(1178): Socket 14 is not connected any more (errno=-1)
[Tue Feb 13 08:36:03 2007][info] ajp_send_request::jk_ajp_common.c
(1202): Error sending request. Will try another pooled connection
[Tue Feb 13 08:36:03 2007][info] ajp_send_request::jk_ajp_common.c
(1225): All endpoints are disconnected or dead
[Tue Feb 13 08:36:03 2007][info] ajp_service::jk_ajp_common.c (1749):
Sending request to tomcat failed, recoverable operation attempt=1
After that, we changed the timeout for tomcat ajp connector (initially =
1) to 6ms.
Now we get other errors:
- a lot of Error decoding request in the JBoss logs at the same times
where mod_jk is showing
[Mon Feb 19 13:25:50 2007][info]
ajp_connection_tcp_get_message::jk_ajp_common.c (955): Tomcat has forced a

Do you have any idea which parameters do we need to change in this
configuration?

Then start reading on
http://tomcat.apache.org/connectors-doc/reference/workers.html
what your configuration means. You will notice, that a value of 2 for
the socket_timeout does not really make any sense.

there is a specific reason for this parameter configuration.
I believe that this should be a default dev configuration.
