If you see Other consuming more space than you're expecting, I would make sure your cleanup script actually cleaned up the old files going back in time instead of just moving forward.
You can check $FWDIR/log to see what's sitting around in there:
If there are lots of old flat file logs still sitting there, maybe try removing some and see if that helps improve your log index retention by relieving some disk space? Usually, I just use the rm command with some wildcard to do small blocks at a time.
