IIS trouble on Exchange server - Application Error - Event ID:1000 - System Log - Warning -WAS EventID 5139 generated at same time.

I have a Windows 2008 R2 DataCenter SP1 running Exchange 2010 SP3 Rollup 14.  IIS 7 is installed too.
Every 20 - 25 minutes I receive about 20 Event id: 1000 logged over a 3-4 minute span.  Then there's peace until the events get logged again in about 20 minutes.  When these application events get thrown I received warnings (5139) in the System log at the same time.
