Large number of UM dial Plans. UM services crashing. RRS feed

  • Question

  • Hi,

    We've been having issues with Unified Messaging on Exchange 2013 SP1 (deployed as a multi-tenant environment). We have approx 860 UM dial plans which create tenant segregation. Exchange 2013 UM is configured with Lync Hosting Pack V2. Everything was working fine, until we got about 200 new organisations, and we created new dial plans associated with them. Now we are seeing the following issues starting the UM service on the Mailbox server, and extremely high memory usage of the UM call router service on the CAS Servers.

    The Microsoft Exchange Unified Messaging service on the Mailbox server ended the process umservice (PID=41232) due to an internal inconsistency or an unrecoverable situation.
     
    The Microsoft Exchange Unified Messaging service wasn't able to start. More information: "Microsoft.Exchange.UM.UMCore.UMServiceBaseException: The Microsoft Exchange Unified Messaging service encountered an error. The worker process didn't start in the allotted time.
       at Microsoft.Exchange.UM.UMService.UMService.InternalStart()
       at Microsoft.Exchange.UM.UMCore.UMServiceBase.StartService()
       at Microsoft.Exchange.UM.UMCore.UMServiceBase.OnStartInternal(String[] args)"
     
    The Microsoft Exchange Unified Messaging service terminated unexpectedly.  It has done this 1 time(s).  The following corrective action will be taken in 5000 milliseconds: Restart the service.

    Thanks in advance.

  • In case anyone stumbles across this tread. After working with Microsoft Premier Support for a few days, it's a confirmed issue within Exchange. Once creating approx ~800 UM dial plans & UM hunt groups the UM service begins to crash and hang.
