mod_jk errors - are these normal?
If our setup was completely stable, and configured perfectly, should there be NO mod_jk errors ever? Or, are some errors part of normal operation? The system seems to work fine from a user's perspective, but we still occasionally get these: [Wed Mar 01 20:00:42 2006] [error] ajp_connection_tcp_get_message::jk_ajp_common.c (961): Can't receive the response message from tomcat, network problems or tomcat is down (10.0.0.9:8009), err=-113 [Wed Mar 01 20:00:42 2006] [error] ajp_get_reply::jk_ajp_common.c (1503): Tomcat is down or refused connection.

But, we also don't have much traffic right now. (Only about 700 visitors a day, with about 15 page views per visitor.) We've ran load tests, but the error message count doesn't seem to inrease by much if any. Are these error messages a normal part of mod_jk, or do they definitely indicate some sort of problem (like network issues)? We are using mod_jk 1.2.15, Apache 2.0.55 and Tomcat 5.5.15. For what it's worth, we have other completely separate system setups using mod_jk2, and they also all seem to get occasional ajp errors. This is our first setup using mod_jk, and we are assuming these errors are a bad thing. Thanks, -Michael __ Do You Yahoo!? Tired of spam? Yahoo!

This is our first setup using mod_jk, and we are assuming these errors are a bad thing. I always had those errors. I did anything i could do - change timeouts, change backlog, change this, change that - whatever - these errors remain. Just make sure, that the tomcat allows as much or more ajp-connctions, than there will be apache-processes/threads. I think the programmers have given up on solving this - whatever the problem is. AFAIK, mod_jk prints that error-messages to the log and then tries another connect which usually works. Actually i hear the developers say: this is not a problem - or something like that.
