'rc.d/squid stop'

[applecom at inbox.ru]

It seems Squid 2.6.6 stops strangely on my FreeBSD 6.2-PRERELEASE box.
Output of '/usr/local/etc/rc.d/squid stop'

Stopping squid.
Waiting for PIDS: 553 564, 553 564, 553 564, 553 564, 553 564, 553 564,  
553 564,
  553 564, 553 564, 553 564, 553 564, 553 564, 553 564, 553 564, 553 564,  
553 564
.

During shutdown proccess initiated by Ctrl+Alt+Del or by ACPI power button  
I see the same.
System says about watch-dog timer after it. Is such squid's stopping  
normal or not?
