Rafal,
See if you have vm.lower_zone_protection set?
# cat /proc/sys/vm/lower_zone_protection
If not set, then set to 100 and viola all your low mem issues should
vanish.
You can use top -p <pid> , for the pid for ocfs2 and see how it
is using memory
But, with RHEL4 to eliminate any source of an OOM - set
vm.lower_zone_protection=100 in /etc/sysctl.conf

Rafal,
What version of Red Hat are you using?
cat /proc/meminfo will show us how memory (Low and High) is doing, top
will show how much a process is using of virtual memory
How much memory? What kernel is being used?

Hi guys
I have 4 node cluster with OCFS2.

My friends suppose that ocfs2 consume memory.
So I have question:
How check how many memory is occupied by ocfs processes?
Is it a low memory?
