I'm trying to just drop a 500mb fulltext index on an older 4.1 MySQL MyISAM table.

When I do it, the cpu pegs to 100% and sits like that for over 10 minutes.

This cannot be normal, right? I gave up and just restarted mysql and index is still there.

There is no message in the error log.

Any other approach I can try?


Nevermind, it took 30 minutes and double the database size in free disk space in the end.

I guess even drop is very slow for some reason (I know building can be, but drop?)
