What kind? Xen, VMware, ...? Is this Linux (what kernel)?

Are you using dynroot? Are you sure your root.afs/root.cell is accessible?

Syslog or dmesg would be more likely to indicate a problem.

To debug... first try running 'cmdebug <client>'; give the output if it
outputs anything (even if it doesn't look interesting).

If you're on Linux and have an appropriately-configured kernel,
'echo t > /proc/sysrq-trigger' will give a trace of all processes in
dmesg/syslog. Put that in a pastebin or something, if you're okay with
giving out a listing of all the processes on that machine.
