[Ocfs2-users] o2net: connect to node has been idle for 10 secs

[Alexei_Roudnev]

Ooo, it is well known (for OCFSv2) message.

Moreover, THIS particular timeout can not be changed.

In my case, after spending few days, I find that my HugeTLB setting (in
Oracle) caused long kernel loop and it forced OCFSv2 to reboot because of
losing connection.

PS. I dream, when I will see a SET of heartbeat interfaces in OCFSv2. It is
THE ONLY system which do not support it (from all clustered systems I have
around). Bonding.. hmm, bonding is for another purposes, and have 20 - 30
seconds reconvergence time by design.
