Hi all:
I have another question.. this time on a panic I received

-------------------------------------------------------------
With what little poking around I have done it looks
like I am out of wired memory...
However the SCTP tests that were running have NO
allocated associations etc.. so I am thinking
I might have a memory leak..
Is there any way to tell what is holding all the memory :-)
Thanks
