Long - The server should halt if sent a SIGTERM (the default of the 'kill'
       command).  You could try 'kill -9' on it.  But make sure it's not
an avoidable thing...

First, check the obvious: inspect your process table to see if the server
process is in a Stopped state: in Unix *maybe* someone did a 'kill -STOP' on it
(use 'kill -CONT' to resume it).

It may be hung on I/O, which could well be a tape drive.  Use the public domain
'lsof' command or other monitoring tool (and, if AIX, errpt) to look for a
problem device.  Also consider:

                                        Unix, you might try using the client on
