UGLY Bug? Squid cant be killed, host cant be rebooted

[Perun]

Hi

I have a problem with squid on 18.1.2_2
If I try to stop it I get these errors (see attachement).

then I cant kill squid process (not either with kill -9):

Code: [Select]

50587  -  D      26:09.05 (squid-1) -f /usr/local/etc/squid/squid.conf (squid)

only reboot helps, but I need to do power off/on because it hangs at shutdown with squid

Can someone confirm that it is a bug? Or do I have something wrong in my config?

Will this not work?

# service squid stop

(takes a long time usually)
