Hi,
We are experimenting with the connectTimeout setting on the tomcat side in
server.xml. We used to have this set to 0 (inifinite), but we were seeing lot
of unused threads and connections on the tomcat side. Thus we set the
connectionTimeout to 200000 (200 sec.). After enabling this I observe in the
mod_jk logging the following lines:
[Wed May 24 14:46:28 2006] [info] ajp_send_request::jk_ajp_common.c (1178):
Socket 78 is not connected any more (errno=-1)
[Wed May 24 14:46:28 2006] [info] ajp_send_request::jk_ajp_common.c (1202):
Error sending request. Will try another pooled connection
[Wed May 24 14:46:28 2006] [info] ajp_send_request::jk_ajp_common.c (1225):
All endpoints are disconnected or dead
[Wed May 24 14:46:28 2006] [info] ajp_service::jk_ajp_common.c (1749): Sending
request to tomcat failed, recoverable operation attempt=1
[Wed May 24 14:46:28 2006] [error] ajp_service::jk_ajp_common.c (1758): Error
connecting to tomcat. Tomcat is probably not started or is listening on the
wrong port. worker=worker2 failed
[Wed May 24 14:46:28 2006] [info] service::jk_lb_worker.c (696): service
failed, worker worker2 is in error state
My question is: Do endusers experience any requests which are failing.
When looking at the mod_jk requestlogging within a few seconds of these error
messages, I only see 200 and 302 resultcodes. When looking at the jkstatus page
I do not see that the worker2 enters the error state.
Configuration:
Webserver: Apache 2.0.58 on Solaris 8 with worker MPM, with ThreadsPerChild
sets to 75
