OK I take back my other innodb comment - it looks like the UBB install overrode my defaults and made all the MYI files and such.
I do still have an ib_logfile0 but it's only 51mb.
I don't have any automated backups running on this server, I am trying to keep activity to a minimum so I can track down what the issue is.
I did just download the MySQL admin tools and will be turning on logging.
If you meant the webserver log files, no those aren't over a gig.
