EOPNOTSUPP (Operation not supported) -High CPU

Recommended Posts

Hi

Server slowing to a crawl (happens a lot) ; trying to trace down source of high CPU usage.

  • problem looks mysql process related.  When I trace the process I see a loop happening over and over with the same error.
  • ran query to show processlist and I don't see anything out of the ordinary.


Any idea how to track down what is eating up my CPU?

Thank you :)

looping error below.
