[Ocfs2-users] out of memory problem concerning 64-bits?

I run 2 OCFSv2 clusters on SLES9 SP3 (last update) on x86_64, and never saw
something like OOM.

Through, when I tested it under a heavy load (I run it on a light load now,
putting heavy load onto traditional ReiserFS and heartbeat cluster),
I noticed extreme CPU usage of the OCFS2 (but never saw memory usage).

(But SLES9 have improved OCFS2 drivers, as I know. Anyway, lOCFSv2 in the
last SLES9 update looks pretty stable. I never installed OCFS2 from
sources to keep system consistant, and it shows some results).
