We've had the same problem here, trying to get HA dns/named service 
working. Works great for a day or so, then seizes up, simple commands 
like `crm_standby -v true` timeout after 120 seconds, etc. We're testing 
for release, and keep running into issues like this. At first we 
suspected firewall issues, but even after confirmed operation and 
several hand-offs of HA services back and forth, it still dies within a 
day or so.

We're on CentOS 6/64 with yum packages augmented from 
http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/RedHat_RHEL-6/
with exclude=pacemaker* corosync*

In order to make the log files visible, I've snipped out a time period 
during which it becomes unresponsive visible at

I don't know the exact moment, this is a test cluster and not being 
monitored by a netmon. Any other details I could provide that would be 
useful/helpful?
