[Ocfs2-users] flock errors in dmesg

[Brian Kroth]

I've been working on creating a mail cluster using ocfs2.  Dovecot was
configured to use flock since the kernel we're running is debian based
2.6.26 which supports cluster aware flock.  User space is 1.4.1.  During
testing everything seemed fine, but when we got a real load on things we
got a whole bunch of these messages in dmesg on the node that was
hosting imap.  Note that it's maildir and only one node is hosting imap
so we don't actually need flock.

I think we're going to switch back to dotlock'ing but I was hoping
someone could interpret these error messages for me?  Are they
dangerous?

Thanks,
Brian
