Furthermore, I can say that I even have more workers than intended: 22972 ?? S 0:02.92 (squid-2) -f /usr/local/etc/squid/squid.conf (squid) 23146 ?? S 0:02.44 (squid-1) -f /usr/local/etc/squid/squid.conf (squid) 23237 ?? S 0:00.74 (squid-coord-3) -f /usr/local/etc/squid/squid.conf (squid) 31139 ?? R 0:00.11 (squid-1) -f /usr/local/etc/squid/squid.conf (squid) 31192 ?? R 0:00.01 (squid-1) -f /usr/local/etc/squid/squid.conf (squid) 31193 ?? R 0:00.00 (squid-1) -f /usr/local/etc/squid/squid.conf (squid) Some of they don't die after squid -k kill, I have to kill them explicitely with -9. Is that normal ? Right now I decided to switch back to non-SMP. And yeah, I just don't like this situation with thousands of open FDs, wich doesn't happen with one worker. Is this resolved in 3.3.x ? Thanks. Eugene.
