HibernateSessionManager and background threads

[Ilya Obshadko <il...@gmail.com>]

I have recently noticed in my GC logs that application leaks memory after
running periodic background process which performs database operations. I'm
suspicious of Hibernate not cleaning up after himself. So the question is:
are there any specific techniques for using Hibernate in background
processes (i.e. via PeriodicExecutor)?

Any suggestions appreciated.

Thanks a lot, that seemed to finally help - instance is now running for 5
days without OOM.

You'll need to @Inject the PerThreadManager and call cleanupThread() in the
finally block of the task(s).
