[OpenAFS] Possible Kernel Memory leak, OpenAFS 1.4.2+, RH3 i686/amd64

[Kevin Hildebrand]

Hello, I've been banging my head on this for a while and thought I'd see 
if anyone else has any clues.

Since upgrading to OpenAFS 1.4.2, both our amd64 and i386 RedHat 3 linux 
platforms have been seeing significant kernel memory leaks.

Namely, the "size-256" slab grows by approximately 4K each time I stat 
files in a certain directory in AFS.  Some of our more active machines 
will run themselves out of memory in a matter of days.

I've tried 1.4.3-rc1 and it exhibits the same behavior.

I have not been able to nail down the exact characteristics of the files 
that will cause this problem- but once I find the appropriate location, 
simply statting files at or below the directory in question is sufficient 
to cause the leak.

If anyone has any clues as to where else I should look, I'd appreciate it.

Thanks,
Kevin
