3391.0. "HELP - disappearing dxterms" by CIM::KAIRYS (Michael Kairys) Tue Sep 25 1990 13:47

    I recently switched my 14 meg. VS2000 from VMS to Ultrix/UWS 4.0
    and am running Mwm from the Motif 1.1 kit. I have a problem with
    disappearing dxterms. I cannot specify a scenario; it seems random.
    The vanished dxterm may have been inactive or it may (in two
    occurances) have been quite busy doing a make. It may have been
    iconized or not. There is nothing, I believe, unusual in my
    environment, either system or user.
    
    I would appreciate any asistance, in terms of pointers to other
    information or suggestions of how I can get more information from
    my system.
    
    Thanks...

3391.1	autologout?	OXNARD::KLEE	Ken Lee	`Tue Sep 25 1990 14:39`	6
	Is it possible that you have some sort of automatic logout activated? Many UNIX shells have this feature. Some system administrators turn it on by default. Ken
3391.2	Not "autologout", if that exists...	CIM::KAIRYS	Michael Kairys	`Tue Sep 25 1990 16:12`	4
	That occurred to me; however, the only such mechanism with I am familiar is the csh predefined variable "autologout", which is not defined in my environment, and may not even be implemented in the Ultrix csh, since I can't find it in the manual (csh(1)).

	If they are crashing, you can find this out by running them manually from the shell and seeing if there is any crash message when they exit. I don't know if these messages should show up in the session manager, but running them in a shell is pretty infallible. If mwm is losing the windows or moving them off the screen or something, you can find them with xlswins. I don't know if this will find unmapped windows, though. Jeff

"/etc/swapon -a" is only a convenience in rc ...it is there so you don't have to type it manually at system startup ( boot). You still need the entries in your config file (as pointed out by .3) so the kernel can deal correctly with your environment. Swapon is only there to enable the swap devices at system startup time. It is also appropriate to note that most swap devices share space (same partitions) with the crash/dump areas. Any good UNIX internals book can help with the above myths...try 'Leffler, McKusick, Karels, Quaterman...Design and Implementation of the 4.3 BSD UNIX Operating System. Chapter 5 gives very good academic explanation. Kris..
