clients with many requests hang as XWin stops serving them

[Wolfgang Beck]

Hi,

I am using XWin 6.8.1.0-8 on an XP laptop as an X-Terminal of a Linux
machine. The machines are connected over IPSec encrypted wireless.
On the XP machine, I start X with X -query linuxserver and can log in
without problems.

The wireless connection is excellent. A contiuous ping shows very few
errors (about 1 in 30 minutes).

However, x clients hang frequently and can only be removed using
xkill. There seems to be some correlation between client activity and
probability of hanging. 'ico' hangs reproducably after 1-5 minutes,
xterm hangs less often but is still a pain to work with. 

netstat -n --protocol=inet (on the linux machine) shows a connection
with a suspiciously full send queue, which is disconnected after
'xkill':

Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address           Foreign Address    State
   

tcp        0  64440 192.168.0.100:36779     192.168.0.129:6000 ESTABLISHED

Using ssh -X from a (XP-)local xterm does not help:
   192.168.0.129:> ssh -X b@192.160.0.100
   b@192.168.100:> ico
   <hangs after a couple of minutes>

What am I doing wrong?
