I am running Bonita 6.3.2 Community Edition, Tomcat 6, Java jre7. Sometimes, on the server, there's a spike in the CPU Usage. As a result, the system hangs. I'm not sure what could be the cause of this, however, based on my understanding of Tomcat, I believe Tomcat could be causing the memory leak. I have a task scheduler set to stop and start Tomcat on a daily basis. I thought this would fix the memory leak but it does not. Moreover, I've noticed that the bonita/temp folder takes up significant amount of space. Could this be the issue?
