This is probably the source of your problems: squid's main process (or
what is reported to be it) is not a child of PID 1. THis means PID 1
will not get SIGCHLD for it, but its parent process, for whatever that
is. This then means PID 1 will not notice that squid is gone and will
eventuall SIGKILL all remaining processes in the cgroup...
