Hi, Thanks for the clarification and this is good to hear. I will try setting the socket_timeout to 200.
I think however that these messages in the mod_jk log are misleading. - Error connecting to tomcat. Tomcat is probably not started or is listening on the wrong port. worker=worker2 failed Tomcat is fine and mod_jk can connect to Tomcat. Only the previously established connections are broken. Could this error message not be logged if a successful connection to Tomcat is established? - service failed, worker worker2 is in error state This info message is probably a result of the error message above and is probably not logged if the above error message if the error message is not logged. greetings Henk -----Original Message----- From: Bill Barker [mailto:[EMAIL PROTECTED] Sent: donderdag 25 mei 2006 5:10 To: users@tomcat.apache.org Subject: Re: Does connectionTimeout > 0 cause failed requests with mod_jk? Yes, it does cause the error in the logs, for the simple reason that Tomcat closed it's side of the Socket once the connectionTimeout was reached. This causes mod_jk to error when it tries to reuse the half-closed socket. Normally, the error is harmless, since mod_jk just reopens a new Socket connection and continues on (with the user never being any the wiser :). If you set the socket_timeout=200 property on the worker, you'll get nicer looking messages in your jk_log. <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] 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.

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.
