Here's what I would suggest:
The big error log build-up that you are experiencing has
been reported several times on these posts. My error log
file is always around 10 to 12 KB, and I think that this
is what most users here have. I know of no software that
would take it out permanently since it is so useful for
trouble-shooting. Your best bet is to delete it
periodically as it becomes too big. It will be re-created
automatically with no data in it.
This is something which will probably be fixed when the
next Beta version or final version come out. I would just
be patient and try to live with it for awhile.
Maybe somebody else can add to this.
Cheers.
