It is very odd that Torque doesn't think that there are jobs running 
there when there are!

Whilst Garrick's mention of max_load will help it would be useful to 
try and track down what's happening with the jobs.

The situations I've seen this happen with are when a PBS script forks 
a process into the background and then exits, or when an SSH/RSH 
based MPI launcher doesn't clean up nicely after itself (Google 
for "mpiexec" for a really nice replacement that uses the PBS TM 
interface instead).

Good luck!
