Sounds mildly expensive for the typical -ls invocation. Maybe another option for that, though (of course, in cases like the one described here, it'd only work on the machine screen's running on).

screen will attempt to recreate its own socket when it receives
a SIGCHLD.

Perhaps we should have some code that looks through the process list, to find screen processes owned by the user, and help the user by suggesting to recreate missing sockets.
Should 'screen -ls' do this?

This seems likely to be an inherent issue with NFS, rather than something we could be expected to fix. If someone can invent a reasonable solution that can work, we'll consider implementing it, but otherwise, we can't fix a problem without a solution, no matter how undesirable the behavior may be. :\

Sorry, I didn't know I was annonymous. I created an account and created this bug.

If I start a screen session from my homedir with the socket dir as $HOME/var/run/screen/S-$(whoami) and then goto another host with the same socket dir, I can wipe out those sockets with screen -wipe.

This makes it hard (impossible) to reattach the screen session on the original host. I do not have any patch to contribute but please consider this.

Let me know if more information is needed.
