Everyone, Thanks in advance for any help. Also I have a gmail invite for the person who has a fix for this if they are interested.
My company has been using Tomcat for several years, but a problem has crept up that we have not been able to solve. Basically, tomcat will stop processing requests for 2-60 second period several times a day. Here is a list of software that we have tried. (Note we have tried changing each key componant to see if we isolate the componant that is the problem, but no luck yet) OS: RedHat 9 & AS3 Threading model: linux threads & nptl JVM: sun 1.4.2_4 & latest ibm Http connector: ajp w/apache 2 and coyote connector JBDC connector 1.0 1. Doesn't always happen durning old gen garbage collection, but does sometimes 2. Before switching to incremental gc we received out of memory errors which resulted in Tomcat completly hanging 3. After switching to incremental gc the effect changed to 2-60 second periods of time that Tomcat won't process request, but it does resume on its' own. 4. Cpu usage for most of the day is less than 20% utiliztion, but when the problem occurs the cpu spikes to 100% utiliztion briefly. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
