I was unable to resume my screen session this morning, even after I killed the old screen -r session.

svtbuild@dvm-2:~/rfs$ screen -r 17757.pts-0.dvm-2 There is a screen on: 17757.pts-0.dvm-2 (11/27/2012 04:49:19 PM) (Attached) There is no screen to be resumed matching 17757.pts-0.dvm-2.

After waiting for a while I was able to resume. How can I do this more reliably?

From the screen manpage:

screen -D -R Attach here and now. In detail this means: If a session is running, then reattach. If necessary detach and logout remotely first. If it was not running create it and notify the user.

As mentioned for the options -D -RR, unless you know the status of your session(s), you should check it with screen -list.
