My day job is titled "Technical Lead, MS UC" - I work with an awesome group of people at CDW, LLC. I’ve been at this gig in one fashion or another since 1988 - starting with desktops (remember Z-248’s?) and now I am in Portland, Oregon. I focus on collaboration and infrastructure. This means Exchange of all flavors, Skype, LCS/OCS/Lync, Windows, business process, and learning new stuff. I have a variety of interests - some of which may rear their ugly head in this forum. I have a variety of certifications dating back to Novell CNE and working up through the Microsoft MCP stack to MCITP multiple times. FWIW, I am on my third career - ex-USMC, retired US Army. I have a fancy MBA. One of these days, I intend to start teaching. The opinions expressed on this blog are mine and mine alone.

Exchange 2010 SP1 UM & UCMAredist.msp

I ran into a bizarre error today.  The client has two full-up DAG servers – all roles on each server, including UM.  We noticed that the UM role would not stay running.  Checking the DR site revealed that the DR server had the exact same set of errors and the UM service would not stay running.  The errors we were seeing are:

(application log, EID 1000, source “application error”)

Faulting application name: UMworkerprocess.exe, version: 14.1.218.11, time stamp: 0x4c5faa82

The Unified Messaging server shut down process umservice (PID=17732) because a fatal error occurred.

The Microsoft Exchange Unified Messaging service was unable to start. More information: "Microsoft.Exchange.UM.UMService.UMServiceException: The UM worker process exceeded the configured maximum number of consecutive crashes, "5".

WFT?!

I could not find anything obvious, and a Google on these items turned up nothing substantive.  I double-checked my install as-builts, verified that the proper prerequisite were met (desktop-experience, speechplatformruntime, ucmaruntimesteup).  I also checked the remainder of the services to confirm that all other Exchange functions were as expected. 

I went down the galgrammargenerator route to rule out corrupt grxml files. I stood up a naked E2010 in a lab, installed the UM role, grabbed the core grxml files and still the UM service would not start and stay running.  I then removed the service and reinstalled, which did not help. 

What DID work was that I remembered that the OCS to OWA integration required a ucmaredist.msp file…so I tried that.  Voila! 

Question to ponder:  why did the lab server install and function properly without the ucmaredist.msp file?  I built the lab server using the same sequence and files as the prod server so as to duplicate the error.

Thank you, thank you.
i just upgraded and added the um role to my exchange 2010 ent. server and was running into this same issue. i downloaded and installed the role, restarted the um service and bam! i was working.

Hey J,

You are the man, this worked like a charm.

Is there any chance you could zip up your grammars xml files and put them up on a file host temporarily? I'm struggling to get my UM service to stay running and would hate to go through the trouble of building a lab server just for it not to work.

I just got asked or my grammar XML files. I will get them available tomorrow f they are still needed,.
