Hmm.... X11 does normally use TCP (listening on port 6000).
Are you seeing the problem only with remote X11 clients, or only with
local ones, or both?
I'm sitting here in front of a diskless Sparc-1 with 16MB RAM, and I've
never seen an overflow error from the le driver with 1.3.1 or 1.3.2, not
even when the transceiver falls off (is knocked off by the cats).
I've even gone back to running my NFS mounts over UDP so that the system
doesn't instantly crash when an NFS server reboots too.
Mind you I've only got a bwtwo frame buffer, so this CPU doesn't have to
do much work, even for X11. I should probably even run rc5des on it! ;-)
It would appear that the local interface "short circuit" routes to the
loopback interface actually work in 1.3.x -- I always use a fully
qualified domain name as my DISPLAY, and yet there's lots of traffic on
my loopback interface (this machine is basically only an X Terminal):

I can't believe netstat still truncates data from columns, even with -n!!!
So many things still to fix....
