Hi,

I am making database charge tests to my Hibernate apllication, and i got an OutOfMemory exception.

I am loading the full database to memory, but the memory occupied by the application+data is bigger than the application only, and the difference is much higher than the size of the database in my hard drive.

I am trying to close sessions, and evict objects, but i am not getting anywhere. Do you know that the cause might be?

Thanks in advance,
Joao Rangel

I'm getting the same error. My take is the session object isnt removing the row objects from its hash. I ran jprobe on this and found the row objects never removed and are all referred to by a hash in SessionImpl.

Waiting for some dev expert help.

I think I detected the specific problem, but I still don't know how to solve it. Session.close() is not realising any memory. Why?

I have the same problem too. I'm using session.evict(obj) to clean up the row object from iternator once I use them. to my dismay, they are still hanging around in memory. the hash table in sessionimpl is holding a reference to them and thus not being cleaned up by the gc.

once the iterator goes thru the whole list, memory will get cleaned up. but when you have a large result set and it fills up your heap you're bye bye
