Error Log System.InvalidOperationException

Hello, 
 
we've been looking through our Error Logs and turns out we are generating about 35MB of activity over any 24 day period. 
 
The generated errors appear to be the same exception over and over again, running 2 seconds apart. 
 
===============================================================
 
System.InvalidOperationException: Instance 'MailService' does not exist in the specified Category.

   at System.Diagnostics.PerformanceCounter.NextSample()
   at System.Diagnostics.PerformanceCounter.NextValue()
   at MailService.MailServerStats.UpdateRealTimeStats(Process mailServiceProcess)

We are not sure how long this has been going on, the only reason we got into those logs is because the server was running heavy on CPU this morning and we started combing through logs to try to identify the issue. 
 
Is this something we need to worry about and is there a way for us to fix it?
 
Thank you all in advance.
