Description

« Hide

After having profiled memory, it seems we have a memory leak in SessionRegistry.

A little test (attached) does a search N times for N threads, and for each search, a OutstandingRequest is attached to the session. After a few thousands of search we fall in OOM. I've put some trace in those methods :
SessionRegistry.addOutstandingRequest
and
SessionRegistry.removeOutstandingRequest

Session Released
addOutstandingRequest 2
addOutstandingRequest 3
addOutstandingRequest 4
... ( 100 requests)
addOutstandingRequest 99
addOutstandingRequest 100
addOutstandingRequest 101
remove session

The SessionRegistry.removeOutstandingRequest is never called, except if an exception is raised (NamingException).

It may be on purpose ( persistent search), but we can't assume the server will be able to hold as many OutstandingRequest as we have search requests - or entries -.
