I like to run CHECK TABLEs every day ... I have a small perl program that does this for me, which I keep meaning to post for download - today's shaping up to be light, so while I'm thinking about it maybe I'll just do it!
Anyway - I agree Mike's suggestion, backup then repair. You could also first run CHECK TABLE <tablename> EXTENDED; http://dev.mysql.com/doc/refman/5.0/en/check-table.html just to get an idea of what you're looking at. On a table your size (111 K records, mostly varchars) I wouldn't think this would take too long but it will lock up things for a little while, so use your judgment as to whether to run during the day. Note it will not fix anything, only report problems. REPAIR TABLE does the fixing. OPTIMIZE TABLE should "defragment" your data and update your indexes. If that still doesn't help, you could either 1) drop the index in question and re-create it, or 2) backup the table by dumping with mysqldump, drop the table, and load from backup dump.

Is there some sort of maintenance i should be running on this db routinely to help this?
