Hi Honza,
A team is already working on moving to the latest linux. However, we
delivered a feature with RHEL6.5, which has run into this issue. Any tip would
be very helpful for us!
It's highly probably caused by corosync, but it's really hard to say,
what patch can help solve problem you hit (we did rebase in RHEL 6.6).
So no real hint. Just upgrade to something supported.
Regards,
Honza
Thanks,
Karthik.

Sorry missed important information.
We are using RHEL6.5 and Pacemaker 1.1.10-14.
6.5 EUS is over (ended November 30, 2015), so it's good idea to update.
Regards,
Honza
Thanks,
Karthik.

We are trying to figure out when is this happening. In the meantime, guidance
from expert users would be very helpful for us. Please let me know if you have
already seen this issue and the probable causes.
Thanks,
Karthik.
