Thanks for that tip. I am sorry I did not write yesterday and today,
but we have so much other problems we did not have time to check
anything yet.
In the mean time I discovered another disaster with TopLink which is
right now my most important problem as I cannot finish another part of
application.
If you could, please, take a look at my recent post about TopLink and
Set<Something> field troubles? I would be very graceful.
Thanks,
Witek

What does your application code look like, what sequence of JPA calls are made when merging/persisting Entities? Do the memory problems exist for both merging and persisting? Is the merge() api used to 'persist' the Entities?
