Summary: Memory leak

Initial Comment:
We are doing massive data inserts by sending xml to a 
servlet that translates this information into item 
creation requests on a stateless session bean who 
interacts (calls create) on a couple of entity beans. 
This worked fine on 2.4.x but on Rabbit Hole the 
memory gets pegged when doing more than 30.000 inserts 
and more (we used to do 50.000 on that same machine 
before without even noticing a performance hit and 
using only a couple of extra percent of memory while 
doing the insert). 

Basically memory usage slowly increases up to 99% and 
the server slows down to a crawl. This memory is not 
recovered after the insert is finished and not 
recovered if JBoss is restarted - it requires a 
complete restart of the machine for things to go back 
to normal.

We have tried to switch the CMP beans to BMP beans but 
get (almost) the same result. i.e. with BMP it goes 
through in 3 hours what used to take minutes and the 
memory is pegged afterwards. On CMP it just slows down 
to a crawl and does not finish after several days (it 
never "fails" (throws an exception) though).

OS: Slackware Linux 8 (kernel 2.4.16)
JDK: Blackdown 1.3.1 and IBM 1.3
