Re: Really Strange Problem

We had this problem on all our redhat servers (with the same symptoms you 
described and very similar timings too) and it was tied to a cron job that ran 
to update the local os index db. Disable mlocate and any other package that 
uses locate in the name. That os job consumes 100% cpu when it runs.

Silly, perhaps, but check the cleaners! It has been known - urban myths
notwithstanding - for cleaners too unplug things to plug in the Dyson.

Now, I'm pretty certain that cleaning staff will  not have access to a
server room, but ...


Cheers,
