[squid-users] Squid -k doesn't work.

Hi everyone. I can't send a signal ( -k reconfigure or -k check .. )
by root to my squid, it works only by squid user.

sudo -u squid -k reconfigure

As you can see, i can read it.

bash-2.05b# whoami
root
bash-2.05b# ls -la  /usr/local/squid/
total 10
drwxrwxr-x   4 squid  squid  512 Nov 13 00:01 .
drwxr-xr-x  17 root   wheel  512 Nov  1 14:31 ..
drwxr-x---  18 squid  squid  512 Nov 13 12:22 cache
drwxr-x---   2 squid  squid  512 Nov 12 12:19 logs
-rw-r--r--   1 squid  squid    5 Nov 13 12:22 squid.pid
bash-2.05b# cat  /usr/local/squid/squid.pid
6990
bash-2.05b# ps -waux | grep 6990
squid    6990 15.8 21.9 234936 227312  ??  S    12:22PM  18:42.82
(squid) -D (squid)
root     9627  0.0  0.1  1592   852  p1  S+    2:50PM   0:00.01 grep 6990
bash-2.05b# squid -k check
squid: ERROR: Could not send signal 0 to process 6990: (3) No such process

/usr/local/etc/rc.d/squid reload  doesn't work too

So i can send a signal like this

kill -HUP 6990

But after that squid doesn't want to work normally ( Simply it doesn't work).
It shows me in cache.log this
