Re: [eclipselink-users] dead lock
|
Hi,
Any information about this problem? I think there is a reliability
problem here :-(

Hello,
Regularly, either our connection pool is fully used, or threads
are waiting for locks. Is there a locking problem in Eclipselink?
We have a big application consisting of about 20 ejb and war
modules packaged in an ear.
I wonder if this is an eclipselink bug there. We only use injected
EntityManager (only 99% sure, as there are many developers
involved).
Here is part of the jstack output. Lots of threads with similar
trace.
