[Ocfs2-users] Big load and many error with ocfs2 1.3.3

[Sunil Mushran]

Are you exporting the ocfs2 volume via NFS? If so, then we did fix this 
issue.
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=592282cf2eaa33409c6511ddd3f3ecaa57daeaaa
It should be fixed in 2.6.22.

Use 2.6.22 + patches as listed in the following link:
