EOVERFLOW while accessing /dev/pts/256

I'm not even sure this is a bug... But it almost looks like that old
pty devices are not reused.
What can I do to regain access to my screen session? Rebooting this
this server would be quite painful.

I tried logging in again and now the shell is using /dev/pty/257 with
minor 1.


When running screen -x:
