Also make sure you are either getting an Container Managed
EntityManager, or you are either clearing the ApplicationManaged
EntityManager or creating a new Application Managed Entity Manager
after commit() otherwise the Extended Persistence Context (Entity
Manager) will continue to grow in size as more objects become managed.

Yeah, we are using multiple transactions, i.e.
get an EntityTransaction
do work
EntityTransation.commit()
set the local tx to null

Is the import all
in one transaction? I'd be curious if you broke up the import (even for
a test) into multiple transactions whether the issue would go away.

Subject: [eclipselink-users] memory usage
I am running a long data import that uses eclipselink 1.1.2 for
persistence. I see memory increasing slowly but surely as it goes
along. The YourKit profiler does not identify anything as a link, but
I do seem to have an increasing "retained size" for
org.eclipse.persistence.internal.sessions.RepeatableWriteUnitOfWork
[Stack Local]
I see there is a clear method on TransactionWrapperImpl, but that does
not seem to be in the JPA EntityTransaction API.
Is there a best practice for long running data imports? Should I be
clearing something?
Thanks.
