Thanks Amos,
Currently I am using Version 3.0.STABLE2 of squid on RHEL5.
I'm not fully certain on it but I think the problem may be related to
another sen in the way squid files certain things in memory an disk. If
the diskd in your case is too slow saving an object before its
invalidated it can be left with a bad filename to deal with.
If AUFS is available on your system I'd try that on a later 3.0, before
STABLE5 things were pretty bad.
FWIW, I have some final adjustments then about to roll 3.0.STABLE9.
