Whenever http://www.k12foodservice.com/ is accessed, Squid restarts with the following message: Jul 21 16:15:40 proxy squid[25842]: Squid Parent: child process 25844 exited due to signal 6 Jul 21 16:15:43 proxy squid[25842]: Squid Parent: child process 26486 started Our setup is somewhat complicated with a Squid process that only does NTLM authentication. The request is then passed to DansGuardian which then passes it to a second Squid process for retrieving the pages. This is on a RedHat ES 4 box with squid-2.5.STABLE6-3.4E.9. I can provide config info if needed. Thanks, ~M
