OOM caused by OpenJPA
Hello All,
We are facing an issue related to OutOfMemoryError exception appearing
intermittently.
We installed a HeapDump analyzer to track the cause of the issue. The
following screen appeared after choosing the dump file that we want to
analyze:
The analyzer suspected a leak in
/org/apache/openjpa/persistence/EntityManagerFactoryImpl caused by openjpa
internal implementation. Could this be the possible cause of our issue? If
so, any suggestion on how to solve this issue?
Appreciate your help.
Thanks,
Hovan Akelian

The problem is that your application is creating EntityManagerFactories,
but they are never getting closed. When you are done using an
EntityManagerFactory, be sure to call .close() on it.
Let us know how it goes.
Thanks,
Rick

Hi Rick,
We installed the heap dump analyzer to track the cause of this issue and
the following screen under this link
<https://docs.google.com/forms/d/1m1p5AdIoFQRnkW38WcO4l7zVOYQubBIymXmoT6sKZP8/edit>
appeared after choosing the heapdump file.
The analyzer suspected a leak in
/org/apache/openjpa/persistence/EntityManagerFactoryImpl caused by openjpa
internal implementation.
Regards,
Hovan

Did you do any sort of leak analysis? If so, what appears to be the
problem? Can you post the heapdump somewhere?

The attachment didn't come through. Can you post it elsewhere so we can
view it? Also, post the contents of your persistence.xml file.
Thanks,
