It means Squid was unable to load a file off disk. As you can imagine
the number of reasons for disk file errors are many, and not limited to
AUFS or even things being done by Squid itself.

We do see it commonly with people first introduced to SMP workers and
still using AUFS (or diskd, or ufs) cache_dir. Only rock type supports
SMP fully, so the other cache_dir types currently need to use the
if-else and ${process_number} config hacks to prevent troubles.
