Hi Merle,
it looks like you solved my problem! I have worked a bit this morning on the remote host, and I had no problems at all. I will continue to work on the host this afternoon and see what happens.
Thanks a lot!
Cheers,

With untrusted connections (which -X implies), there is apparently a timeout which kicks in after which no more connections are allowed (see the paragraph under ForwardX11Trusted in the ssh_config man page).

To investigate the problem I have created a new user on my local machine (under Mac OS X 10.6.7), and it appears that the problem doesn't occur with this new user. It makes me suspect it might be a permissions problem, but I am not sure which are the files involved, and I can't find any log from X11 which could help locate the problem. The thing is that X11 does not crash or complain of anything: if I open another connection, everything works fine... for a few minutes. Does someone have any idea where that could come from?
