FWIW, I'm still having this problem.
I've completely dropped the table and re-built it from the ground up.
It's a bizarre problem... The table is totally simple. A primary key,
and then three varchar fields. The FULLTEXT index spans the 3 varchar
fields. There are only 6500+ rows, so it's pretty tiny.
A mysqldump of the table is only 442K.
Has no-one else seen anything like this? I can't imagine I'm the only one.
Thanks,
Don
