Very low, so this sounds like a likely possibility. The partition
filled up while I was browsing / downloading a set of large files (4Mb
or so each).

No core file, just a 500K squid cache index. I'm 95% sure I started
with a clean cachedir while using 1.2beta18 due to the warnings in
the 1.2 notes about changing formats. I then skipped 1.2beta19
and jumped to 1.2.20+patch.

4K per inode. An 'ls -R | wc -l' gives 34000, so I guess taking a 4K
average unused space (worst case), this gives ~130M accounting
difference between the sum of byte lengths and the disk usage.

Obvious when you have the answer to the problem waved under your nose.

Thanks Duane,

(busy reformatting with 1K blocks, and setting cache_dir back to
200Mb)
