[jboss-user] [JBoss jBPM] - out of mmory error

[asubu]

Hello All,
I downloaded the jbpm-starters-kit-3.1. I was able to create my own process and upload it to the server. The server was running fine for a day then all of a sudden started throwing the exception shown below:

11:12:49,788 ERROR [CommandExecutorThread] java.lang.OutOfMemoryError: PermGen space
11:12:54,788 DEBUG [JbpmContextInfo] creating jbpm context with service factories '[message, scheduler, logging, persistence, authentication]'
11:12:54,788 DEBUG [JbpmContext] creating JbpmContext
11:12:54,788 DEBUG [DbPersistenceServiceFactory] creating persistence service
11:12:54,788 DEBUG [DbPersistenceService] creating hibernate session
11:12:54,788 DEBUG [DbPersistenceService] beginning hibernate transaction
11:12:58,898 DEBUG [CommandExecutorThread] command 'null' threw exception. rolling back transaction
java.lang.OutOfMemoryError: PermGen space

At this stage all the jbpm has is the websale and my own created process.

My java options are set the following:
set JAVA_OPTS=%JAVA_OPTS% -Xms128m -Xmx512m
Has anyone experienced such a problem?
Also I see a scheduler constantly running every 5 seconds. What does this do?
Regards,
Subu
