Hi all,

We have X11 Rel 4 PL14 running on Sun SPARCstations 1, 1+, and 2 running
SunOS 4.1 and 4.1.2.  We noticed a strange problem lately that we
have not been able to isolate yet.  After invoking xinit and a
couple xterm's, we receive a message "Can't open display" after
a few minutes.  The error occurs when we try to invoke another X
client.  This occurs even if the workstation is idle after the xterm's
are invoked.  Nothing else is running on the system other than the 
normal SunOS processes.  I think the message is coming from the server.

I have seen this message before only when trying to make the condition 
occur (i.e., invoking many X clients to determine the display limit).

Can anyone provide some insight into this problem?

My next step is to debug the server which could be time consuming.

ADDITIONAL INFORMATION:
xinit sets the DISPLAY environment variable to unix:0.0.  Even if I
invoke xinit -display hostname:0.  If I changed DISPLAY to 0:0 or
hostname:0 in the xterm window, then I can invoke X clients from that
xterm.  STRANGE.  The following are the DISPLAY values and the result
from executing a X client:

DISPLAY=unix:0		Can't open Display
DISPLAY=unix:0.0	Can't open Display
DISPLAY=:0		Can't open Display
DISPLAY=:0.0		Can't open Display
DISPLAY=      	 	Can't open Display
DISPLAY=hostname:0	Can't open Display
DISPLAY=0:0		Can't open Display
DISPLAY=0:0.0		Can't open Display

Side Note:
1. I didn't realize DISPLAY 0:0 is valid for X11R4.

2. Why is DISPLAY = unix:0.0 even after xinit -display hostname:0?

3. Why does 0:0 or hostname:0 work where unix:0.0 does not?

Thank you,
Richard Jackson
