Re: duplicate key error on autoincrement field while inserting
What operating system are you running, and how big are these files and indicies? Is this a 2 Gig file size limit problem? You are getting near the limit to the size of an unsigned mediumint.

Re: duplicate key error on autoincrement field while inserting
OS Is Linux. The autoincrement key is defined as INT, so plenty of room there. Table sizes are getting up there: attempt.MYD 1,902,291,232inrec.MYD 1,979,795,600 attempt.MYI 280,733,696inrec.MYI 240,460,800 After doing a myisamchk -r on the attempt table, inserts appear to be working again, so I would't think the huge file sizes are the problem (yet). No recovery was done on the inrec table, but after doing a FLUSH-TABLE, an insert worked on that table as well. Don't understand that one. I still point back to the fact that 2 different tables had autoincrement problems at virtually the same time. And this is the only app running on this system. Why did MySql decide these 2 keys already exist when in fact they don't?
