Yes. Once the cache is full, the LRU time reflects the amount of time
for an object to pass through the cache. That is, the difference between
the time it is removed to make space, and the time it was fetched.

Sounds like you might have a dodgy kernel version, or a dodgy disk. One
or two versions of squid also tended to commit minor filesystem sins, as
well. What version of squid are you using?

Unlikely. Hitting file-descriptor limits should not corrupt your
filesystem, unless your kernel is buggy.
