[Mauiusers] error with maui

[Yanan Sun]

I am a newbie to torque/maui. we just installed the torque/maui in our
linux sever. it seems that they are on.

[root at master]# ps aux |grep pbs
root     23475  0.0  0.0   8972   812 ?        Ss   09:53   0:00 pbs_server
root     27371  0.0  0.0  60236   748 pts/18   S+   10:47   0:00 grep pbs

[root at master]# ps aux|grep maui
root     27366  0.0  0.0  60232   744 pts/18   S+   10:46   0:00 grep maui
root     27738  0.0  0.2  43268 23596 ?        S    Jul02   0:21
/usr/local/maui/sbin/maui start

however, when i type  showq, it gives me error message.
[root at master]# showq
ERROR:    lost connection to server
ERROR:    cannot request service (status)

and another error message when i trying to restart maui
[root at master]# /usr/local/maui/sbin/maui restart
ERROR:    cannot open user interface socket on port 42559

i killed the pbs_server by "qterm -a quick" and start it again by
"pbs_server". still the same problem. what should i do?
Thanks.
