Torque (formerly SPBS) is very stable, especially since we helped the 
SuperCluster folks clobber the various memory leaks in the server.

Our pbs_server has been running for almost a month now since I last restarted 
it (because I was doing a bit of system maintenance, not because of PBS 
problems, I think it'd been running for about 2 months before that) and it's 
only VSZ 3148 and RSS 2136. :-)

NB: I'm still running an SPBS release from early November as that's when we 
fixed the last memory leak and it's worked like a dream since then.

I believe it's on the SuperCluster folks list of things to do, but they've 
been busy working on the stability front (as well as MAUI and Silver).

CC'd to the SuperCluster folks so they can respond.

No idea, don't use it.
