How do I kill a dead screen session?

[allen@mmbp ~]$ screen -ls
There is a screen on:
    3634.wb_backend (Dead ???)
Remove dead screens with 'screen -wipe'.
1 Socket in /var/run/screen/S-allen.

I tried screen -X -S 3634.wb_backend quit and here is the result:

There is a screen on:
3634.wikibrain_backend  (Dead ???)
Remove dead screens with 'screen -wipe'.
No screen session found.

I tried screen -S -X wb_backend kill and here is the result: mkfifo /var/run/screen/S-allen/27272.-X failed

This (Dead ???) session used to be an Attached session and I used:

screen -X -S 3634.wb_backend kill

to kill it. It ended up to be in this weird status.

I have tried:

screen -wipe

but it didn't work.

How could I terminate it?

Answer 1

screen -wipe PID

will wipe the dead screen.
