Hi there,
since I upgraded to 3.1 (both .6 .9 and .10) have such problem.
After I issue "squid3 -k shutdown", the squid will exit but the
process won't stop after it clams "exit normally"
The process will still use 100% cpu and network connections are not
closed due to output of "netstat"

I'm running squid on a virtual machine ubuntu 10.04. Here attached the
exiting log.
