[Ocfs2-users] OCFS 1.2.4 memory problems still?

[Cline, Ernie]

The latest of kernel as well:
Linux cyber2.petersons.net 2.6.9-42.0.8.ELsmp #1 SMP Tue Jan 23 13:01:26
EST 2007 i686 i686 i386 GNU/Linux

For how long do you want that?  I'll let it run over the weekend.

Start monitoring /proc/slabinfo and /proc/meminfo. Dump it to a file 
every 5-10 mins.

Which version of the rhel4 kernel are you on: uname -a?
