We have an intermittent problem where one of the servers will have an
unusually large number of running processes for a minute or two, which
will slow down response time.
By unusual I mean like 50-100 processes fighting for CPU time; normally
there are just a handful. The cause of this isn't entirely clear yet.
My pure speculation is that the squids might be distributing traffic
poorly; for instance the NFS server occasionally freezes up for a
couple seconds, which might cause the squids to give up on all of the
servers, then start sending all traffic to the first one that responds.
Maybe? Maybe not. Just speculation which I haven't gotten a chance to
investigate.
