Abstract
For passive detection of live systems during controller failover in a distributed environment, a set of member systems is sorted according to heartbeat periods used by members in the set of member systems. An amount of elapsed time since a failure of a first controller system in the distributed environment is determined. From the sorted set, a first member system is selected due to a first heartbeat period of the first member system being a shortest heartbeat period in all heartbeat periods in the sorted set of member systems. Using a processor and a memory at a second controller system, a timeout period is computed. The timeout period is an amount of time remaining in the first heartbeat period after the amount of elapsed time. The first member system is removed from the sorted set after the timeout period expires and the first member system has not sent a heartbeat.
