Ocfs2 users - May 2007 - Out of memory (with 2.6.20)

Hi, I have a two node OCFS2 cluster. I'm using the OCFS2 version included
with
the kernel 2.6.20, as it's shipped in the Debian distribution.

My system runs out of memory after several hours (three or so) of intense file 
copying (rsync).

I'm attaching the contents of /proc/meminfo , /proc/slabinfo and free just 
before the crash.

AFAIR there were some similar problems in a previous OCFS2 version but I 
thought it was already fixed.

Best regards

Nope - those patches made themselves into 2.6.21, so you're just a bit late
I'm afraid.

Not to worry - I've backported them (and a bunch of others) for 2.6.20 - you
can find a patch at:

http://kernel.org/pub/linux/kernel/people/mfasheh/ocfs2/backports/2.6.20/ocfs2_2.6.20_fixes-20070502-1.patch
