Thanks for the kudos.  I ordered 64MB sticks to add to all my printers and 108 
512MB RAM
sticks for all my clients yesterday/this morning.  So by tomorrow afternoon 
these
problems should mostly go away for me.  But this doesn't mean it should be 
forgotten as
this appears to be a very big problem for LTSP and seems as though it will 
continue to
get worse, possibly preventing LTSP from being stable at all on lower memory 
client (bad
for a large part of the world).

So now I am hammering on xorg to get a fix to limit the amount of RAM available 
for
pixmap storage (I was slammed on the list stating pixmaps are not cached but 
stored). 
This may be a better workaround than limiting RAM usage in general.  I doubt it 
will go
anywhere.  But at least if that was done client stability could be fairly 
stable and if
an app lost stability then that could be dealt with on more reasonable timeline.

Jim
