I am unable to get more than five clients to run using ISC's Xvga server. Has
anyone come across such a phenomenon and can offer me some advice? I have
RTFM and they suggest:
(1) do a netstat -m to check STREAMS resource usages.
I have done this and there have been no failures to allocate resources.
(2) check how many pseudo terminals have been configured.
I have sixteen ptys configured but the largest number of xterms I have
been able to start is 5.
(3) check the values of NOFILES, NPROC, MAXUP
I have and they all seem fine.
So does anyone else have any suggestions? Please help as this is driving me
crazy.

Here is a sample of my .xinitrc that starts up zillions of things (I have a 19" 1600x1200 monitor, so I can start lots of things and still have room) Good luck. Sample .xinitrc file: userresources=$HOME/.Xresources usermodmap=$HOME/.Xmodmap sysresources=/usr/lib/X11/xinit/.Xresources sysmodmap=/usr/lib/X11/xinit/.Xmodmap HOST="`uname -n`" # # The following two variables are used to pause the software initializations # between each step. When too many things are started at the same time, the # server gets screwed up and gets into a state where all new connection # requests just hang (i.e. they are not refused, but they never succeed nor # timeout). # # Set both to nothing (comment them out) if your server does not have this # problem # SLEEPCMD=sleep SLEEPTIME=7 case "$DISPLAY" in unix:0.0|unix:0|:0.0|:0) DISPLAY="${HOST}:0";; esac DISPSET="-display ${DISPLAY}" # merge in defaults and keymaps if [ -f $userresources ]; then xrdb -merge $userresources fi if [ -f $sysmodmap ]; then xmodmap $sysmodmap fi if [ -f $sysresources ]; then xrdb -merge $sysresources fi if [ -f $sysmodmap ]; then xmodmap $sysmodmap fi ${SLEEPCMD} ${SLEEPTIME} # # set bell frequence, and duration # xset b 95 1200 150 # # start up motif windo manager # mwm & ${SLEEPCMD} ${SLEEPTIME} # # start up clock # xclock ${DISPSET} -update 1 -g 75x75+95+0 & ${SLEEPCMD} ${SLEEPTIME} # # start up load average windo for this system # xload ${DISPSET} -update 2 -g 250x75+190+0 & ${SLEEPCMD} ${SLEEPTIME} # # start window that shows who is on the system on virtech (and beeps when # the list changes) # xterm -n "who's on virtech" -T "who's on virtech" -geometry 37x10+720+0 \ -e remsh virtech TERM=xterm DISPLAY=$DISPLAY /usr/local/bin/whoson & ${SLEEPCMD} ${SLEEPTIME} # # start up big local window (iconified) # xterm -n 'ender 96x64' -T 'ender:xterm #1' ${DISPSET} -geometry 96x64+0+110 -i & ${SLEEPCMD} ${SLEEPTIME} # # start up mail notifyer for my virtech mailbox # rcmd virtech "xbiff -update 1 -file /usr/mail/$LOGNAME ${DISPSET} -geometry 75x75+0+0 &" ${SLEEPCMD} ${SLEEPTIME} # # start up load average display for virtech # rcmd virtech 'xload ${DISPSET} -update 2 -geometry 250x75+455+0 &' ${SLEEPCMD} ${SLEEPTIME} # # start up three xterms that are rlogged into virtech (iconified) # xterm -i -n 'virtech 96x64' -T 'virtech #1' ${DISPSET} -geometry 96x64+0+110 -e rlogin virtech -e & ${SLEEPCMD} ${SLEEPTIME} xterm -i -n 'virtech 80x44' -T 'virtech #3' ${DISPSET} -geometry 80x44+912+530 -e rlogin virtech -e & ${SLEEPCMD} ${SLEEPTIME} xterm -i -n 'virtech 80x30' -T 'virtech #2' ${DISPSET} -geometry 80x30+912+16 -e rlogin virtech -e & ${SLEEPCMD} ${SLEEPTIME} # # start up the login xterm (iconified) # exec xterm -i -geometry 80x24+0+0 -name login -T login -- Conor P.

While the X documentation lists suggested settings for system tunables and pseudo terminals, these settings will not be optimum for every installation. If you experience problems such as not being able to open more than a certain number of windows, you may have to adjust tunables up or increase the number of pseudo terminals configured. Try increasing NUMSP first since that is the one related parameter not automatically increased during X installation. ... SUP
