793.0. "Disconnected from TPU if > 30 min," by 51336::P_SUNDSTROM (Peo Sundstrom SSG/VMS Sweden) Wed May 17 1989 05:22

	I have a question about TPU in decwindows environment.
	TPU is started with the symbol declared as: 

XTPU == "SPAWN /NOWAIT/INPUT=NLA0: EDIT /TPU /DISP=DECWI /NOCREATE -
	/SECTION=SYS$LOGIN:TORGNY_EVE.TPU /INIT=SYS$LOGIN:TPUINI.TPU"
	

	The session ends after about 30 minutes with the following message.

	XIO: non-translatable vms error code: 0x2DBA002, vms
%decw-e-cnxabort, connection aborted
%XLIB-F-IOERR, xlib io error
  TORGNY     job terminated at 25-APR-1989 16:13:03.60


	Is there anyone who knows what causes this error?

	The system is running VMS 5.1 SDC.

793.1EVETPU::TANNENBAUMex-TPU DeveloperThu May 18 1989 01:039
    It looks like an XLIB problem to me.  I've had versions of DECwindows
    TPU hang around all day without any problems under V5.1 and T5.2 FT2.
    One this evening even rode out a cluster transition (we rebooted one of
    the two boot members in a 33 node LAVc)
    
    Any suggestions from the XLIB gurus?

793.2more info maybe37404::boniniYou are only coming through in waves...Thu May 18 1989 11:3611
	We are using the TCP/IP transport for DECwindows VMS and see
the same error occasionally.  It never happens with DECnet and only
happens intermittently.  Very rarely, the transport will work.  
Sometimes it hangs, sometimes we get the error in the previous reply.

	We can easily reproduce this also if someone cares to do that
for debugging purposes.

	Hope the additional info is useful.

    re .2:  Would you execute a "mc ucx$ucp sho dev" command on the server
    node running with tcp/ip and see of the devices attached to port 6000
    have the 'KEEPALIVE' option set?

793.4Some more info51336::P_SUNDSTROMPeo Sundstrom SSG/VMS SwedenThu May 18 1989 12:4112
	I just will give some more info about the environment.
	The workstation involved is a VS2000 with 14 Mb memory
	and no local disk. It's booted from a VAXserver 3600 with
	RA 82 system disk. There are about 10 more workstations booted
	from the same 3600. Most of the workstations don't have any local
	disk for pageing and swapping.

	Is it possible to set up the workstation so it won't be disconnect
	the TPU sessions ??

793.5edit/tpu/disp/decw and moving cursor = same error51336::P_SUNDSTROMPeo Sundstrom SSG/VMS SwedenTue May 30 1989 11:4522
	 Hello again!

	 I found out that moving the cursor up and down	several times 
	 causes the connection to abort with the same error.

	The problem is reproducible at will. The Display is created as
	Set display/create/node=mumble/transport=decnet.

	The editing is started at a client and displayed at a vaxstation
	2000 display server.
