Emmanuel Lecharny updated DIRSERVER-644:
----------------------------------------
Attachment: SearchTest.java
The test used.
> Memory Leak in Persistent search ?
> ----------------------------------
>
> Key: DIRSERVER-644
> URL: http://issues.apache.org/jira/browse/DIRSERVER-644
> Project: Directory ApacheDS
> Type: Bug
> Components: core
> Versions: 1.0-RC3
> Reporter: Emmanuel Lecharny
> Assignee: Alex Karasulu
> Priority: Blocker
> Fix For: 1.0-RC4
> Attachments: SearchTest.java
>
> 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 -.
