1.1.0p6 is really old.  There have been countless improvements since

Is pbs_mom running on grid1?  Is pbs_sched running on the server?

Is grid1 a node or server?  The information above is confusing.

The server logs indicate that it is a node.  The MOM config looks like
grid1 is the server.

And you don't need the $restricted line, that just weakens security.

These kinds of things are just config errors that are hard to diagnose
over email.  Eventually the admin figures it out and doesn't tell anyone
