Well, I checked PID and TIME of my helpers: itag_auth.pl(indicated
as myaclhelper.pl above), but they did not change. So I don't think
my helpers are destroyed and newly spawned... And also, I think squid
dies, whenever one of helpers dies or exits(I'm running squid with -X
and -N options and it functions in this way as far as I know.)
[korekawa@squid ~]$ ps aucx | grep itag
squid 15961 0.0 1.2 7412 3104 ? S 17:07 0:00 itag_auth.pl
squid 15962 0.0 1.2 7404 3048 ? S 17:07 0:00 itag_auth.pl
squid 15963 0.0 1.2 7404 3048 ? S 17:07 0:00 itag_auth.pl
squid 15964 0.0 1.2 7404 3048 ? S 17:07 0:00 itag_auth.pl
squid 15965 0.0 1.2 7404 3048 ? S 17:07 0:00 itag_auth.pl
How do you think? Or any other possible reason for kicking helpers so often?
Thanks.
