We are running five apache 2 web servers which all load balance between 12 tomcat 5.0.28 app servers all on SuSE 9.3 machines. We are experiencing occasional problems with tomcat not responding to the apache servers. The apache/logs/jk.log reports "[error] ajp_service::jk_ajp_common.c (1758): Error connecting to tomcat. Tomcat is probably n ot started or is listening on the wrong port." every few seconds. When we access tomcat through the tcp/ip connector port, it responds correctly. If we try to access the AJP/1.3 port from a browser, the browser never connects. When the server is not causing problems, the browser connects and generates a Severe error in the catalina.out file. The only solution we have found to remedy this problem is to stop and restart the tomcat server, often having to resort to a kill command to terminate the process. I've seen this issue discussed on various sites but most of the discussion concerned some bugs in Red Hat's thread libraries. If any one has experienced this problem, I would appreciate your input. I can send config files for analysis. Thanks, Eddie Dimond
