    Oh, I did have one question about the Window Manager, too.
    
    What is the purpose of the two additional windows that are the size of
    the root window?  I have heard them called pseudo-root windows and I
    have seen them accessed by the background setting programs, but what
    are their exact purposes?

    1.  I think it is actually 31.  There may be problems with other
    	quotas (Biolm, Fillm, etc.) on either the client or server side.
    	Once-upon-a-time, I had 20 xclocks up on my server running from
    	four different machines.
    
    2.  Nope, hard coded.
    
    3.	The maximum size is transmitted by the server to the client at
    	connection setup time.  This is 16KB with a VMS server.  The VMS
    	Xlib will break large requests into smaller pieces either into
    	multiple requests or multiple I/O's depending upon the request
    	type.

    Good info, but puzzling.
    
    I've ANALYZEd the system and looked the processes involved. All quotas
    and limits look fine.  I've also tried boosting the values for the
    server with no change.  I can still only get 15 connections.  The
    changes that I made for the server were as follows:
    
    DIOLM   from  100 to 200
    BIOLM   from   60 to 150
    BYTLM   from 50000 to 75000
    
    I also check GBLPAGES and GBLSECTIONS and they're not bad either.
    I ran all the clients detached so that quotas would not be depleted
    due to SPAWNing.  I tried accounts with much smaller quotas and they
    could only connect 15 times.  It sounds system wide.
    
    Any suggestions?  Oh, could you run the connection program to see
    what your max connection is?
    
    Thanks,

	/* Sleep for ANALYZE/SYSTEM */
	sleep(10);

}

    
    I made a slight change.  Try this version.

}

    Great! Now, I see the error...
    
    %SYSTEM-F-EXENQLM, exceeded enqueue quota
    
    I first looked at the process but that was not it.  It was the
    ENQLM of the SERVER that was the problem.
    
    Thank you very much for all the help!

The server has two locks for each local client, one queued and one granted.
This is not true for DECnet clients (or TCP, I suppose).

    Any takers for RE: .1?
    
    The purposes for the two "root window" sized windows of the window
    manager.
