Hi all, I'm currently experiencing frequent (about once per week) hangs of a server that is about 1500 kilometers away from me. I have a serial cable on the box, and using minicom on the neighbor box I am now in the kernel debugger - but I'm at a complete loss as to what to do to figure out what is, in fact, wrong. Calling panic or boot doesn't work - it just stops at "syncing disks..." and never actually reboots. I suspect something fishy going on with disk I/O, but I can't be certain of that. The box responds to ping - until I call panic or boot - but no other services are working. What can I do? I'm now at the db> prompt ... Help :) /Eirik
