You might experience unwanted server restarts if you have activated the service watchdog utility.
In certain circumstances, if the response time exceeds the watchdog timeout period, the watchdog utility can falsely detect a JVM error, which causes a server restart.
The problem occurs when the Orchestrator server is running with a heavy load, for example if you have connected Orchestrator to many vCenter Server instances that are running many virtual machines, or if the server is performing swapping.
If you experience this behavior, extend the watchdog timeout period by increasing the timeout parameter in the wrapper.conf configuration file. If the problem still persists, deactivate the watchdog utility by setting the timeout parameter back to zero (0). See Activate the Service Watchdog Utility.
