Hi, I've recently taken over support of a system using mod_jk. This is a big website utilising 2 sites, 2 web & 3 app servers per site. each web server talking to 3 app servers The site takes millions of hits per day.
I'm getting the above info message regularly (twice a minute) even in the night where the site is relatively lightly loaded. The full report is :- [Tue Mar 20 08:27:46 2007][24590:14016] [info] ajp_send_request::jk_ajp_common.c (1215): (app103) error sending request. Will try another pooled connection [Tue Mar 20 08:27:46 2007][24590:14016] [info] ajp_send_request::jk_ajp_common.c (1241): (app103) all endpoints are disconnected [Tue Mar 20 08:27:46 2007][24590:14016] [info] ajp_send_request::jk_ajp_common.c (1244): (app103) increase the backend idle connection timeout or the connection_pool_minsize [Tue Mar 20 08:27:46 2007][24590:14016] [info] ajp_service::jk_ajp_common.c (1930): (app103) sending request to tomcat failed, recoverable operation attempt=1 My workers.properties config is (per web server) worker.app101.lbfactor=1 worker.app101.socket_timeout=6 worker.app101.socket_keepalive=true My JBoss server.xml connector has got <Connector port="8009" address="${jboss.bind.address}" emptySessionPath="true" enableLookups="false" redirectPort="8443" maxThreads="1000" acceptCount="200" protocol="AJP/1.3"/> Exact config :- apache 2.0.52 (stock RHEL4), mod_jk 1.2.21 (built from source), JBoss 4.0.3 I note that the connection_pool_minsize should not be increased on Apache 2.0. I also understand the backend idle connection timeout defaults to 60 seconds so it does seem that increasing it doesn't sound sensible. I can't say the above error is definitely causing problems though we're getting occasional reports of long delays. Any help would be much appreciated as I'm under a bit of pressure to try and sort. Thanks Rob
