Shaunt Libarian - Did you ever get a resolution to this? I'm seeing the same issues on one of my Front Ends.

 

Thanks!

    AM_RSR580 , what is the faulting module path in your instance?  I ran across this once, and it was related to having UCMA Runtime 5.0 (version would be 6.0.9319.x) installed along with UCMA Runtime 6.0 (version would be 7.0.2046.x).  In that instance, there were also some Skype for Business Server 2015 items installed (Debugging Tools).  

     

    Resolution in that instance was to uninstall Skype for Business Server 2015 components installed and UCMA Runtime 5.0.

     

    Hope this helps.
