Hi,
We're working on a new Exchange 2013 CU2 migration on Windows Server 2012 from Exchange 2007 SP3 on Windows 2008. We have two Exchange 2013 physical servers running CAS and a single DAG (2 servers 1 DB) with a 2008 R2 witness server. Everything seems to be working fine but we are getting the following events every few minutes in the event logs on both servers. I've searched high and low and can't seem to find a resolution. Any suggestions?
Event ID 5011 from the Source WAS with this info:
A process serving application pool 'MSExchangeSyncAppPool' suffered a fatal communication error with the Windows Process Activation Service. The process id was '21380'. The data field contains the error number.
