Jan 09 2018 21:41:13 [BrightmailScheduler_Worker-33] [ScriptHelper] ERROR - com.symantec.smg.controlcenter.BrightmailException: The Agent running on 127.0.0.1 is temporarily unreachable. Please check the specified host. ; nested exception is: java.net.SocketException: Connection reset

Cause

Network security scanners can, over time, cause the agent service on Messaging Gateway to become unresponsive. 

Resolution

The workaround is to restart the agent service on each SMG scanner, one at a time. This should alleviate the issue temporarily.

On the command line run "service agent restart".

This issue will be addressed with a future release but until then it's best to exempt port 41002 on the Messaging Gateway from internal port scans.
