Fixed. We don't see any memory leak in the server.
Closing the bug, open a new bug if it is seen again.

Gow,
Is the OOM kill of glusterfsd happen again? do we still have memory leak with the product? In all my testing with recent code base, never observed memory leaks. I assume all these memory leak bugs are fixed. Can you confirm its fixed ? Its been 3months since this bug is left open. We need to close it.
