Jobs in the main queue (ss) can have the same jobid
as an active job in a sub queue (sv).
Removing a job with lprm (from a remote host) with a
certain jobid will result in both the job in the main
queue and an active job in the sub queues to be removed
if they have the same jobid.
1. make jobid unique
2. make lprm not desend to sub queues
