Server Local Connection Provider has stopped listening on local pipe due to a failure
Had this for the first time in x years. Happened about the same time as the log backups.

However, I also got the Severity 17 alert email which had an additional bit of information:


  Comment: Error 17 - Insufficient Resources.


Am investigating but it currently looks like this is connected to Shared Memory and IIS logging. The suggestion I found was that IIS on the server (VM) had run out of memory.

Might be worth sending yourself the alert by email (Severity 17) to see if you do get more information - may help you determine the cause. Meanwhile, I'll keep digging into why I got mine...
