Hello,
I have a problem here with:
[root@ablprx01 squid]# cat /etc/*release CentOS release 5.2 (Final) [root@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@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@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@ablprx01 squid]# ifconfig eth0 Link encap:Ethernet HWaddr 00:16:35:5B:39:AE inet addr:10.121.42.32 Bcast:10.121.255.255 Mask:255.255.0.0 inet6 addr: fe80::216:35ff:fe5b:39ae/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:989588 errors:0 dropped:0 overruns:0 frame:0 TX packets:1150056 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:590019020 (562.6 MiB) TX bytes:639895003 (610.2 MiB) Interrupt:185
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
