Sure, here are the processes after each step that would cause a change: Step 3: 1879 ? Ss 0:00 /usr/sbin/squid3 -YC -f /etc/squid3/squid.conf 1881 ? S 0:00 (squid) -YC -f /etc/squid3/squid.conf 1890 ? S 0:00 (digest_pw_auth) -c /etc/squid3/digest Step 5: 1879 ? Ss 0:00 /usr/sbin/squid3 -YC -f /etc/squid3/squid.conf 1881 ? S 0:00 (squid) -YC -f /etc/squid3/squid.conf 1890 ? S 0:00 (digest_pw_auth) -c /etc/squid3/digest Step 7: 1879 ? Ss 0:00 /usr/sbin/squid3 -YC -f /etc/squid3/squid.conf 1881 ? S 0:00 (squid) -YC -f /etc/squid3/squid.conf 2237 ? S 0:00 (digest_pw_auth) -c /etc/squid3/digest And the pid file never changed from 1881. Let me know if you want an strace or anything else. --Will
