chkrootkit "The tty of the following user process(es) were not found"

[Adam Funk]

Whenever I have jobs running overnight in screen while I'm logged out,
I get things like the lines below in the chkrootkit output e-mails
(plus the commands running in the screen shells).  Sometimes they
include commands with passwords as arguments --- obviously not a good
thing.  I've never seen one that I didn't expect, apart from the
strange /usr/bin/X thing, which sometimes appears as keeps appearing
until the next reboot.  Is there any way to suppress them?

Thanks,
Adam
