Connectivity not stable (Unreachable Cannot connect)to an instance -Getting ComException in the log

The monitor will stay connected for a while, then break in the WHI/Ping groups. The common message is: COMException The remote procedure call failed and did not execute. (0x800706BF)

Sometimes it will self resolve after a long period of time, or if I force a retry on the connection it usually will come back for a while. Repeat this cycle over and again.

Recent changes in our environment include some firewall items, but wouldn't that lead to NO connectivity as opposed to limited or intermittent?

Thanks for any help

Good Morning and thanks for your inquiry with SQL Monitor.
Can you try increasing the memory quota for WMI to see if that helps?

Thanks, I did change the setting, but I need to wait until our next outage window so the server can be rebooted. I'll report back if this helps with the issue
