I am getting Exchange errors repeatedly through out the day. Both are Event ID 1006 and come from MSExchangeDiagnostics.
Environment
Windows 2012 (not R2)
Exchange 2013 CU3
VMWare 5.1
C: drive has 38GB free (38% free)
D: drive has 1TB free (99% free)
I've posted the event log entries below. I know I can edit Microsoft.Exchange.Diagnostics.Service.exe.config to disable the alert, but that is not really a valid solution, just a work around. I'm posting this mainly because I want MS to be aware and to fix the problem, or at least explain what is causing this alert, i.e., what is the trigger threshold. But if anyone knows how to actually fix this please let me know.
