How can I prevent segfaults, general protection faults, 'Watchdog: Daemon died, rebooting...', and unexpected reboots from clurgmgrd or rgmanager in a RHEL 4, 5, or 6 cluster

Solution Verified - Updated -

Issue

  • Why do I see "Watchdog: Daemon died, rebooting..." on a cluster node?
  • cluster node unexpected reboot by clurgmgrd watchdog
  • A general protection fault occurs and watchdog message is printed which resulted in the cluster node rebooting:
Oct 30 18:30:04 node1 kernel: clurgmgrd[9805] general protection rip:3e9e2729ed rsp:43bc4b50 error:0
Oct 30 18:30:04 node1 clurgmgrd[10484]: <crit> Watchdog: Daemon died, rebooting...
  • An update to our /etc/cluster/cluster.conf file results in a segfault and reboot of a server.
