Dear all,

does anybody know what could have caused the 'Connection refused' 
messages given in the
server_logs section below. Any job submitted to the batch queue stucks 
with status 'Q' instead 'R'

Please note that
- pbs_server, pbs_sched and pbs_mom are installed on the same computer 
- there is no firewall running on the system (OS = SLES 9)
