     I've got a daemon process who runs (theoretically) until the
     machine drops -- it's our mail-daemon. The daemon transfers
     
     In the usual course of events the client (my long-running
     daemon) connects to a server (the decnet object on the
     remote machine); they talk back and forth; and finally close
     the decnet link. However, occassionally the client may have
     
	     a) On the client machine the daemon has closed the
     link 
     b) On the server machine the server has finished execution and
     also closed the link (it's long gone).
     d) On the client machine ncp:"show known links" shows a Decnet link
     still in place between client process (which is still
     
     This is a particularly nasty situation for we ultimately run
     out of Decnet links which, so far as I can tell, aren't
     really attached to anyone!

from the networking guide (vms) pg. 2-41:
(some stuff not included)

Then, when the logical link is disconnected, the "object" program (such
as FAL) terminates, but the process is not deleted.  Instead, control returns
to the NETSERVER.EXE program, which asks NETACP for another incoming logical 
link request to process.  This cycle continues until NETSERVER is
deleted after a specified time limit.  The default is 5 minutes.  To use
a different default time limit, specify the logical name
NETSERVER$TIMEOUT, using an equivalence string in the standard VAX/VMS
"delta time" format:  dddd hh:mm:ss.cc

The effect of NETSERVER is to reuse network server processes for more than
one logical link request, eliminating the overhead of process creation for an 
often-used node.
