Hello,

The below exception is being resulted on Production Environment. This was not encountered in any other environments like Developmen, System Testing, Operations Acceptance Tesing, UAT, Beta Testing.

The below are the details about project servers / frameworks:

Frameworks used: Spring, Hibernate,3.1.2
DB server: Oracle9i
App Server: WebSphere6.1
Workflow: JBPM-3.1.3
Application Server: WebSphere6.1

Please find the below error encountered and advise for any further information required.

I have been advised by jbpm experts that i could get some help from Hibernate experts and hence posting the issue here.
Can you please advise how to go about on this problem?

I think the problem is that there are two different applications on the server under different users that want to write their files into the same directory (java.io.tmpdir). So the second is not able to read/write the files from the first application due to file system restrictions (cache files are owned by user one).

I have the same problem, but have not found a way how to solve it. You could set the <diskStore path="xx"/> to another directory, so no conflicts between your app and the other exists.
