Exchange server cannot be connected by remote

Question

I have a DAG environment for Exchange 2019 CU13, consisting of two servers. Recently, the servers have been unable to remotely black screen. Unless a forced shutdown and restart are used, I am unable to log in to the server. I have noticed some related errors in Exchange during this period, such as event ID :4999 Watson report about to be sent for process id: 20728, with parameters: E12IIS, c-RTL-AMD64, 15.02.1118.037, M.E.Diagnostics.Service, M.E.Diagnostics.PerformanceLogger, M.E.D.P.PerformanceLogSet.ConstructDataCollectorSet, System.OutOfMemoryException, f32a-dumptidset, 15.02.1118.037.

Hi @姚黎忠

Recently, the servers have been unable to remotely black screen. Unless a forced shutdown and restart are used, I am unable to log in to the server.

According to your description, this issue may be more a windows server issue than Exchange issue.

And since there are OutOfMemoryException errors in the logs, I will suggest checking the resource utilization (like CPU, memory) on the Exchange servers when this issue occurs.
