I think I may have killed my APM. I installed SP3 and now see the following when attempting to connect on the web int.
APM Service Not Available
The Web Console is unable to communicate with the APM Service Engine.
There is an error in the event view that states the following:
Unhandled Exception caught in APM Service Engine startup. Cannot listen on pipe name 'net.pipe://localhost/orion/apm/businesslayer' because another pipe endpoint is already listening on that name.
