Memory leak in ADS ?
--------------------

                 Key: DIRSERVER-681
                 URL: http://issues.apache.org/jira/browse/DIRSERVER-681
             Project: Directory ApacheDS
          Issue Type: Bug
    Affects Versions: 1.0-RC3
            Reporter: Emmanuel Lecharny
            Priority: Blocker


When doing thousands of searches, at a point, the memory get exhausted, and the server stop
to deliver responses.

The first bet is that we have a memory leak somwhere. Using yourkit shows that the heap increase
continuously while search requests are being processed.

However, I have done an extensive test whith all cache set to 1, and launched an heavy test
(100 000 random search requests over a 10 000 entries base), with a Heap size set to 25 M,
and everything is running fast (even if it's slow).

So the second bet would be that cache setting is to big in regard to the allocated memory,
and we just exhaust memory using too much cache.

I will try to do a 12H test with 1 sized cache tonite, and a 48H test with 100 sized cache
on tuesday and wenesday, to check which hypothese is the good one (hope the second will be
it :).
