Nethanel Wizman commented on AXIS-2863:
---------------------------------------
Well done Andreas!
The version you delivered works perfectly.
I tested my system with the new axis version for the last 24 hours with load
test and the memory consumption was very low and very stable.
I also examined the objects that were my leak suspects and couldn't find any
circular references there.
There are no huge objects in the memory anymore.
Just to be sure I just went back to the old version and reproduced the memory
leak.
I want to thank you for the fix, good work :-)
Nagaraj - I think we can be reasured that this problem is behind us. Let us
know how your tests worked.
Thanks again,
Nethanel
