gfs2 generates stack trace when openais is stopped on RHEL5

Issue

As part of a  simulated a fencing test, the openais service was stopped in the active node(Node2) so that secondary node(Node1) will take over all the services and will reboot the active node(Node2).
Node1 takes over the services, but the following errors occur.

agent "fence_ilo" reports: Unable to connect/login to fencing device 


 "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
