Question : Restart Server hangs

I have a server (NetWare 6 SP5, Dell PowerEdge SC1420) that doesn't cooperate when I issue a "restart server" command.  It's my GroupWise server, MTA, POA, GWIA, WA.  The server experienced a critical error recently after reloading GW Web Access.  When I attempted to Restart Server, the response was:
Module JAVA.NLM unloaded
Down server? y
Module NLSTRAP.NLM unloaded
Processor 1 is offline.
GWINTER: Initiating termination sequence...

The server hangs at this point, until I power it off and back on.  This is inconvenient as the server is in a branch office.  Can anyone assist me in fixing this?  thank you

Answer : Restart Server hangs

I always find it's best to shut down each system prior to issuing the "restart server" command.

The problem, as I see it, is that loading GWWA threw a critical error, and you didn't clean up after it before trying the "restart server."

Are you running your GroupWise stuff in a separate memory space?  It makes it easier to kill half-dead processes if you use that nifty feature - all you have to do is kill the memory space.  In theory.
