[OpenAFS] Possible Kernel Memory leak, OpenAFS 1.4.2+, RH3 i686/amd64
Mon, 19 Feb 2007 15:42:10 -0500 (EST)
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.
