I don't think it's halted, I think it's cluttered by invalid syscalls.
Secondly, any userland process can make the system unresponsive, by bad
coding. Just write /tmp and /var/tmp full. It's not so hard.
I don't think that's the case here though. Any of you guys logging netstat -m
output every 500ms? Maybe you can see mbufs being drained just before the
system stops servicing syscalls.
