Exchange 2010 14.3 Build 123.4
Stumped. Can't seem to figure out why this suddenly started but this Exchange error is logging every minute.
According to Process Explorer, this is the Exchange process (PID 6860) not logging correctly:
c:\windows\system32\inetsrv\w3wp.exe -ap "MSExchangeServicesAppPool" -v "v2.0" -l "webengine4.dll" -a \\.\pipe\iisipma54689d0-13bc-4c77-a060-0bae334c1a34 -h "C:\inetpub\temp\apppools\MSExchangeServicesAppPool\MSExchangeServicesAppPool.config" -w "" -m 0
This is the error logged:
