Corosync sometimes hangs inside libqb. I've looked at a hanged process with gdb, and I think I've found the problem.
The problem is the loop here: https://github.com/ClusterLabs/libqb/blob/v0.16.0/lib/ringbuffer.c#L451
This was fixed in 0.17.0, see: https://github.com/ClusterLabs/libqb/blob/v0.17.0/lib/ringbuffer.c#L451

I think bumping to 0.17.0 should fix this (at least in backports? Please?)
