When you are getting disk quota errors, be sure that your server is not out of space, or you do not have a limit on the number of files allowed. I've been using the spider friendly URls for some time now without issue. I think most of the bugs with them have been squashed. I tried plenty of stupid things with them <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />
[EDIT]
In addition, the UBB cannot lie about Disk problems. If you are seeing Disk Out of Space, or Disk Quota exceeded errors, those are coming from the Operating System, not the UBB. You need to address those with your host.
