www/squid does not shutdown via rc

[Marko Cupać]

Hi,

I am building new proxy server based on FreeBSD 10.1-RELEASE and latest
squid from ports (squid-3.4.11).

Squid starts and works ok when testing from single client, but it does
not shutdown correctly through rc script.

Starting situation: squid is not started, no pid dir and file in /var/run,
ps ax shows nothing related to squid.

Next: squid is started with 'service squid start', pid dir and file are
created in /var/run, 'service squid status' shows the same value as
pidfile:

% sudo service squid status
squid is running as pid 770.

% sudo cat /var/run/squid/squid.pid 
770

% ps waux | grep squid
squid  768   0.0  1.0 62096 10488  -  Is    3:14PM  0:00.00 /usr/local/sbin/squid -f /usr/local/etc/squid/squid.conf
squid  770   0.0  1.8 82948 18764  -  S     3:14PM  0:00.36 (squid-1) -f /usr/local/etc/squid/squid.conf (squid)
squid  772   0.0  0.3 23876  3012  -  I     3:14PM  0:00.01 (logfile-daemon) /squid/logs/access.log (log_file_daemon)
squid  773   0.0  0.3 23872  3000  -  I     3:14PM  0:00.01 (unlinkd) (unlinkd)
squid  774   0.0  0.3 24256  3024  -  S     3:14PM  0:00.01 diskd 788484 788485 788486

The problem arises when trying to stop squid:

% sudo service squid stop
Stopping squid.
Waiting for PIDS: 770.

Let's see if rc script finds it running:
% sudo service squid status
squid is not running.

There is no pid dir and file in /var/run/

However, ps shows running proceses:
squid  768   0.0  1.0 62096 10488  -  Is    3:14PM  0:00.00 /usr/local/sbin/squid -f /usr/local/etc/squid/squid.conf
squid  806   0.0  1.8 82948 18764  -  S     3:18PM  0:00.21 (squid-1) -f /usr/local/etc/squid/squid.conf (squid)
squid  807   0.0  0.3 23876  3012  -  I     3:18PM  0:00.01 (logfile-daemon) /squid/logs/access.log (log_file_daemon)
squid  808   0.0  0.3 23872  3000  -  I     3:18PM  0:00.01 (unlinkd) (unlinkd)
squid  809   0.0  0.3 24256  3024  -  S     3:18PM  0:00.01 diskd 825348 825349 825350

Those are probably relevant:

Could it be that I am doing something wrong or is this a bug?
