> 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  .

| Emmanuel,
It would be really interesting to see what Jester
would do with ADS:
http://jester.sourceforge.net/
I'm going to start experimenting with it soon, but I
thought I'd throw it out there for the sake of
awareness.
Cheers,
- Ole

This seems a good idea ! But be aware that we have around 7500 java
files, and less the 1400 tests. So there is quite a chance that we don't
have a 1:1 ratio
As soon as you discover that only 1/6th of the code is tested, you will
have to write the missing 6100 tests (supposing that each class is
tested by only one test ;)

| Excellent - I'll work on the 6100 tests tonight and
try out Jester tomorrow :-)
