(I've done exhaustive web searching on this and some articles have pointed to possibly a Quartz issue or Hibernate queries not flushing.

So, I know this is a long post - but I don't really know where to go from here. I've done heapdumps then ran them through the Memory Analyzer in Eclipse (nothing new found there), I've used jconsole with jtop to look at threads - nothing jumps out, thus why I continue to be curious if it's a java/jvm issue. The CPU usage has climbed to the 90s, then it seems to clear itself out again. This does seem more stable and has been up for about 4 hours. I changed the nf, set env variables, cleaned and rebuilt, and started. Hoping for more stability, I decided to change my app to run on the previous JDK that was still installed - JDK 1.6.0_04. Java HotSpot(TM) Client VM (build 19.1-b02, mixed mode, sharing)Ĭould this difference be causing a JVM conflict of sorts? JAVA_HOME and my PATH variables both point to the correct JDK installation.

Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Thus, I get different versions when I do a java -version versus javac -version java -version Then I was digging around some more and found a JRE 6 Update 24 installed on the server (I didn't install it as I do thorough testing with each java update - but maybe my server admin did the update). I was also having trouble with high memory usage, but that has stayed fairly normal and steady since I so-called got the JVM to 'cycle' (bad terminology perhaps, but this is really what it seemed to do - and in the wrapper log there was a dump of all the classes it was reloading after). However, then it started to creep up again, finally going into its 99% CPU usage breakdown. Through a combination of things I'm not quite sure of, it seems like I got the JVM to cycle itself and the app was hovering in the 10-30% CPU usage range for a couple hours. I had to restart midday yesterday, then at 2:30 this morning, then today I could barely restart the application and open jconsole to monitor it before it was hitting 99% CPU usage again.

I was seeing catch issues here and there leading up to yesterday. Tomcat 6, running as service using Wrapper I have a java application that runs on Tomcat (which runs as a service on Windows), the java process for which continues to eat up CPU before eventually requiring me to restart the Tomcat service.
