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. -- Mel Problem with today's modular software: they start with the modules and never get to the software part.
