I have: apache 1.3.33 tomcat 5.0.28 mod_jk 1.2.14 which was installed a year ago when tomcat was added to the whm addon modules. It was running great with low usage. Now the load is a little higher and now I have apache and/or tomcat locking up after some time of activity. I am familure with apache and tomcat settings with regards to memory and I know this is not the issue. What I am having an issue with is tcp sockets from apache to tomcat. When I do a netstat I see a growing number of ESTABLISHED tcp connections. Eventually tomcat begins to fail when the maxThreads is reached for the connector. I have been trying for 2 weeks to figure this out by researching on the net. Basically the threads in tomcat are listing with a status of K - keepalive. Any one experience this? Is this an issue with apache 1.3.33 and mod_jk? Should I upgrade to apache 2? Any help is greatly appreciated.
