[squid-users] Squid stopped working after cache.log and access.log rotation

[Eliezer Croitoru]

There is another option!
The log rotate script is doing something nasty or the systemd service file start up squid in a weird way.
The output of:
$ systemctl status squid
$ top -n1 -b
$ ps aux
$ df -h
$ netstat -ntulp
$ lsof -n|egrep "proxy|squid"

How many clients this system has?
Is the system facing the Internet directly or behind some nat(aws or another provider)?

The above are the basic required data to understand the situation.

All The Bests,
Eliezer

Hi All

We recently installed Squid 3.5.12-1ubuntu7.3 on Ubuntu 16.04.2 LTS.  It ran fine at first but stopped working after a while.   telnet server 3128 still works, i.e., opens a blank window, but Squid is just not accepting requests.    Then we realized that there is no new access.log file.   The access.log file stopped rotated at 6:24AM on 3/17/2017.    It looks like Squid wasn't able to create a new access.log?  We could not find any error message in syslog or the cache.log.      We haven't rebooted the server because we want to know what went wrong.   It isn't the firewall blocking Squid because Squid was working fine all the while until recently.  Also after it stopped working, we disabled the firewall to see if it would work but it still didn't work.

root at paproxy:/var/log/squid# ls -alt

Any ideas what went wrong?

Thank you very much in anticipation.
