[Zaphod-Users] Queue

[George Hurtt]

(1) I tried "showstate", and got this response...

ERROR:    cannot send request to server h101:42559 (server may not be 
running)
ERROR:    cannot request service (status)

(2) Is there a way to estimate the length (time) of the cue? Our group 
has had jobs sitting there for over a day. Can each processor handle 
more than one job?
