Hi all:

I have another question.. this time on a panic I received
its:
-----------------------------------------------------
Unread portion of the kernel message buffer:
panic: kmem_malloc(4096): kmem_map too small: 83386368 total allocated
cpuid = 0

-------------------------------------------------------------

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
