Control center cannot communicate with Messaging Gateway scanner


Article ID: 170788


Updated On:


Messaging Gateway


The Messaging Gateway (SMG) control center is unable to communicate with the SMG scanner resulting in a number of potential issues:

  • Message audit log queries fail and / or are delayed or spin indefinitely.
  • Cannot propagate configuration changes to scanners
  • Unable to view Message Queues


2018-01-09T21:41:13+05:30 (ERROR:2422.54671328): [33048] Error creating new connection: Unknown error 336150661.


Jan 09 2018 21:41:13 [BrightmailScheduler_Worker-33] [ScriptHelper] ERROR - The Agent running on is temporarily unreachable. Please check the specified host. ; nested exception is: Connection reset


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


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.
