Email Listener going down
SA-18428
Summary
User has an Email Listener configured which polls the server every 15 seconds. Some times, the listener is going down with error count in System Management Application (SMA).
When the log files were checked at the time when error occurred, the reason implies to Socket Time out Exception.
When we restart the listener manually, the listener keeps running.
Kindly advise how to automatically restart the Email Listener?
Is there a way to configure some Agent which tracks the Listener status and restart it?
