Once up on a time back in teh original request this was a DNS and disk and
origin server combo problem.
The DNS part is now resolved AFAICT. Apparently the disk bit too.
Now it is just down to the origin server being weird and the thread going
way off track.

Not RAID-0. Worst possible config.
Cheap drives are best with a JBOD configuration, one cache_dir each.

10K HITS ? over how long a period? Squid can suck in that many within a
minute or so on modern server hardware. Then overload a 100Mbps NIC sending
the file data from a cache_mem. Have not seen it replicated on Gbit-E cards
yet.
