Hi all,

I'm a newbie maui admin.  Maui seemed to be working and scheduling
jobs according to my maui.cfg until this morning when I tried to
restart it when I made a change to the config.  Obviously I have
reverted to the known working config, but I still see these errors. 
The funny thing is that jobs are still being scheduled.  Any pointers
as to where to look for more info on this would be greatly appreciated
or if I have missed something in the manual, please let me know. 
Also, I am unsure of what other info might be helpful, so if I haven't
included enough info, please let me know that too. :)

I have restarted the compute nodes and the problem continues, btw.

Maui Scheduler version 3.2.5p2 (it came with oscar).  Both pfilter and
iptables are off on all nodes.

pbsnodes -a shows all nodes are free.

pbs_server logs just show:
11/11/2005 11:58:19;0040;PBS_Server;Svr;b01l02;Scheduler sent command time
11/11/2005 11:59:19;0040;PBS_Server;Svr;b01l02;Scheduler sent command time
11/11/2005 12:00:19;0040;PBS_Server;Svr;b01l02;Scheduler sent command time

pbs_mom log on the first node shows:

In the maui logs, I see many of these:
11/11 11:52:54 ALERT:    cannot accept client on PBS sched socket

Thanks for any information at all.  I am really at a loss here.

Thanks,
Jennifer
