Issue/Introduction

After upgrading Internet Gateway to 8.5 RU1 version (in this case 8.5.3643.0), the gateway service periodically stops and does not restart.

Windows event logs show event 7023 "The Symantec Management Platform Internet Gateway Service terminated with the following error: An exception occurred in the service when handling the control request". 

There was some type of internal 30 minute timer involved within the application.  We see on the settings tab for the gateway Manager that there are some configurable intervals.  Two suspects are status report interval (15 min) and AutoRefresh (30 min).

Note: This issue is still present even after checking a previous known issue reported under TECH251954

Cause

Known issue. The problem is that gateway service is not able to perform service restart gracefully. The restart is triggered by Gateway UI that periodically updates CRLs etc.
If you leave the gateway UI opened, it causes the problem.

Environment

Gateway 8.5 RU1 version (8.5.3643.0)

Resolution

This issue has been reported to the Symantec Dev team. A fix has been already added to the ITMS 8.5 RU2 release.

The current workaround is to close the gateway UI (don't leave it open for long periods of time).
