update media runs alot and zaps cpu

[kyfalcon]

My update media runs way too much and graps most of the cpu. Brings the system to a crawl

[tschak909]

How is your IOWait percentage in TOP during UpdateMedia's run?

943 minutes seems awfully long

[tschak909]

Your iowait is still below 10% which, while it isn't waiting on I/O, it's still nominal..it's okay.

what about the cpu that high for that many minutes

[tschak909]

no. UpdateMedia is very active, and once it finishes a run, it pauses for two minutes before it starts another run.
