Going a bit crazy, random lockup
A portscan of the machine shows that all the proper ports are open.All services however go offline. I have another machine in the same rack and even trying to SSH from that one into the locked up one does not work. Machine will respond to all pings though.
dmesg and /var/log/messages show's nothing at all
always takes a reboot to fix the problem
no major changes to the system at all latetly
