I've seen this problem reported about 4 times in the last week, once in
French. Please don't consider this an authoritative response, because I
have not yet investigated it much, but it appears that you have an
unclean shutdown, and the scoreboard file, which was created the first
time, cannot be created again, because it already exists.

See if you can find the scoreboard file - See what the directive
ScoreBoardFile is set to, and if this file is going away when you shut
down. Experiment with removing this directive, and seeing if that works
(memory-based, rather than file-based, scoreboard).

One more thing - we discussed this at some length on IRC - it seems that
RedHat 8.0 is shipping Apache with mod_unique_id enabled, although lots
of people have no idea what the module is, or what they are doing with
it. If you fall into this category, try removing that module from the
AddModule section of your configuration file. I'm told it's a useful
module. However, in my experience, removing it has solved a number of
problems for some people - specifically, people who are not using it for
anything in particular, so for whom it is not correctly configured.
Besides, if you're not using a module, it's best to not have it loaded
anyway, largely for performance reasons.
