Your system might be running out of memory.
Beware: When squid receives a -k signal, squid may grow a lot for a
while. I had a similar problem; I used a high cache_mem, almost filling up
all the available RAM; but my server have a short swap space.
By midnight, when the system issue a -k rotate, the squid crashed. The
first solution was to use the sleep_after_fork, but it didn't revealed
useful.
The effective solution was reduce drastically the cache_mem to a number
which, the process size x 2 can be fit into the avail sys RAM + swap.
