Fedora (and others) have log rotation and cleaning procedures.

MRTG's file may end on .log, but it isn't such a file which needs to
be removed.

Perhaps someone (you, or some script's author) goofed up and touches
MRTG's log file.

Fedora's log rotation if fine for stuff like apache's html log files.
It should not interfere, in any way, with MRTG's data files.

P.S.
I think, in retrospect, Tobi should have named those files *.data
instead of *.log
