RE: [eclipselink-users] memory usage

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.
