RE: [squid-users] squid stopped responding if internet link iscongested

Ya. I tired killing PID file also, but it didn't help.
I will take output of strace -p pid and send it to forum.
What else should I check?
Thanks - Lokesh

This is strange. Squid doesn't define where traffic gets routed to, it's
a task for the operating system... in such occurrences, can you
determine what squid is doing (for instance by attaching to the process
via "strace -p <pid>")?

Have you tried kill? kill -9? If neither works it means that the OS has
put squid in an unstoppable state, which is pretty weird and usually
only happens in case of NFS timeouts...
