Troubleshooting: Device Maintenance Windows not Working in Resource Manager 5.0.7

Applies To

  • Resource Manager 5.0.7


Maintenance windows in Resource Manager 5.0.7 are based on UTC time, not the local time.  If any other time zone is assumed by the administrator when the maintenance window is created, Resource Manager maintenance windows appear to fail.

Note: This is a known issue with Resource Manager 5.0.7 that will be addressed with a future update.


  • Device maintenance windows sporadically working
  • Device Production State does not get changed to maintenance
  • Log entries similar to: DEBUG zen.Schedule: Never going to run Maintenance Window


To ensure that Resource Manager maintenance windows work correctly, create maintenance windows based on UTC instead of the local time zone.

Note: Watch this KB for updates concerning fixes for this issue.
