Description: During the health check process, if a particular compute node, storage server, or switch does not respond to the health check command within a pre-defined duration, Oracle EXAchk terminates that command.
Cause: To prevent the program from freezing, Oracle EXAchk automatically terminates commands that exceed default timeouts. On a busy system, Oracle EXAchk terminates commands when the target of the check does not respond within the default timeout.
Action: To avoid runtime command timeouts from occurring during health checks, ensure that you run the tool when there is least load on the system.
