The problem may be due to your two lines:
        REGISTER       vc/1    CFUNCTION GLOBAL symlink vc/1 tty1
        UNREGISTER     vc/1    CFUNCTION GLOBAL unlink  tty1

It's possible that you're repeating the "symlink vc/1 tty1" action
many times, because the "vc/1" regular expression will match "vc/10",
"vc/11" and so on, as well as the intended "vc/1". You have a number
of alternatives:
        REGISTER       vc/1$   CFUNCTION GLOBAL symlink vc/1 tty1
        UNREGISTER     vc/1$   CFUNCTION GLOBAL unlink  tty1

this will anchor the '1' at the end of the path. Or, much better to do
this:
        REGISTER        vc/1$          MKOLDCOMPAT
        UNREGISTER      vc/1$          RMOLDCOMPAT

which will use the recommended MKOLDCOMPAT and RMOLDCOMPAT actions.
Even better is to just use:

        REGISTER        vc/.*          MKOLDCOMPAT
        UNREGISTER      vc/.*          RMOLDCOMPAT

like the sample config file recommends. Why would you want to do
anything else?
