Re: [squid-users] squid-2.5.STABLE10 error (FATAL: xcalloc: Unable to allocate 1blocks of 4108 bytes!)

    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.

    Rodrigo.
