[jboss-user] [JBoss jBPM] - Couldn't find ProcessDefinition or load Process Instance by

[bloreguy]

I am using Jbpm 3.2.2 with Jboss 4.2.2 with MSSQL with JTS Drivers.

Worked perfectly with MYSQL with no issues and see error when migrated to MSSQL/JTS Drivers

Very sporadically and with increasing frequency, I see this error:

COuldn't find ProcessDefinition on this call:

graphSession.findLatestProcessDefinition("testSystem");

Couldn;t load ProcessInstance of id '128' with this call:
jbpmContext.loadProcessInstance(128);

If I restart the server, the same call works and all data is present in the database.

Any pointers deeply appreciated. Basically, need help in determining how to isolate and debug this error. Is the session really closed? if so, how do I determine what caused the session to close?
