How to remove an error message in the bottom-line?

Hello:

How do I remove this message from the bottom line in screen:

    "Message 12549 of 12584 bytes to small"

I have a screenrc file from here:

    # Hide hardstatus: ctrl-a f
    bind f eval "hardstatus ignore"
    # Show hardstatus: ctrl-a F
    bind F eval "hardstatus alwayslastline"
