At one of my installs, we've begun to see this error on both the primary and secondary system:
iSCSI Failover: Primary node: Serivice is under heavy load or the time values you have set are too low (interval 5400 ms). Please see Failover Configuration help for further details.
The system load on both nodes appear very low. We are currently running b4550.
I'm not sure how to interpret this error. What is the "service" under load?
