over ssh, After some minutes Gtk-WARNING

Question

I connect to a server over ssh with

ssh -CX server

ok, And I launch remote graphical apps, ok. But after some minutes I get

Gtk-WARNING **: cannot open display

And I have to reset the ssh connection.

Added some outputs

$ echo $DISPLAY; echo $XAUTHORITY
localhost:11.0

$ xauth list
machine/unix:12
machine/unix:10
machine/unix:11

What application is producing this message? What do you mean by “I have to reset the ssh connection”: do you mean you can't start new X applications, or that all X applications crash, or that the whole connection including the command line is terminated (with what error message if any)? — Gilles 'SO- stop being evil', Jul 31 '11 at 17:46
Please post the output of `echo $DISPLAY; echo $XAUTHORITY` in a working connection and in a failed connection. Also, the output of `xauth list | awk '{print $1}'` (anonymize machine names if you like). — Gilles 'SO- stop being evil', Jul 31 '11 at 18:02
Is that in a working or failed connection? And please post the other one as well, the point is to compare the two. — Gilles 'SO- stop being evil', Jul 31 '11 at 18:12
Does it happen after it's idle for a certain period of time? Have you tried replicating it with -vvv turned on in your ssh session? — Matt Simmons, Aug 02 '11 at 03:57

I added this to my .ssh/config

host myHost                                                           
user myUser
port 22
hostname ipHost
