I have a couple of thoughts here.
First, there is the MS rollup that I would recommend installing. This does require a reboot.
Second, clear out the power shell event viewer.
Finally, there is a EdgeTranspot.exe.config file located in the bin directory.
Open it in Notepad, there is a value called "EnableResourceMonitoring" the default for this is True. I would recommend to change this to False. The default values for resources are very low, meaning Exchange will stop functioning if it hits the threshold.
Please let me know the results.
Thanks.
Patty
