Subject [jira] Commented: (DIRSERVER-681) Memory leak in ADS ?
Date Mon, 24 Jul 2006 06:03:14 GMT
    [ ] 
Emmanuel Lecharny commented on DIRSERVER-681:

The server is now running for more than 7 hours, with 5 clients searching for random entries.
The cache has been set to standard value.

So far, it's seems to be perfectly ok. We may not have any memory leak, or at least not an
important one.

The test will be running 11 more hours.

>          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 :).
