[Ocfs2-users] o2net_idle_timer

Hello, I've setup multiple SLES 10 boxes for a OCFS2/Linux-HA solution
but i'm having some difficulties with o2net. Just one pair of boxes
work with OCFS2/Linux-HA.

I really need some help in this because I don't know what's different
in the only pair that it works except SLES 10 only got heartbeat* and
ocfs2* updates and the others got full updates.
