Hello,
I have a problem here with:
[root at ablprx01 squid]# cat /etc/*release
CentOS release 5.2 (Final)
[root at ablprx01 squid]# rpm -qa|grep -i squid
squid-2.6.STABLE6-5.el5_1.3
The web proxy process (used by 300-400 users)
seems to run ok:
[root at ablprx01 squid]# ps uawwwx|grep squid
root 2304 0.0 0.0 7792 1268 ? Ss 08:45 0:00 squid -D
squid 3082 27.7 0.9 46912 37068 ? R 10:21 32:18 (squid) -D
squid 3083 0.0 0.0 1508 232 ? Ss 10:21 0:00 (unlinkd)
[root at ablprx01 squid]# netstat -an|grep LISTEN
tcp 0 0 0.0.0.0:8080 0.0.0.0:*
LISTEN
tcp 0 0 0.0.0.0:3128 0.0.0.0:*
LISTEN
.........
but periodically it will stop working
(web pages can't be displayed).
The "service squid restart" command
will display a lot of dots ..... but doesn't
help and I have to reboot.
I've checked /var/log/messages and also
/var/log/squid/* but don't see any warning there.
ifconfig doesn't report any errors:
[root at ablprx01 squid]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:16:35:5B:39:AE

and the disk space is plenty.
Has anybody had a similar problem and
how would you debug it please?
Thank you for any hints
Alex
