mySQL auto increment problem: Duplicate entry '4294967295' for key 1

Question

I have a table of emails.

The last record in there for an auto increment id is 3780, which is a legit record. Any new record I now insert is being inserted right there.

Answer 1

I had the same problem with the exact same number. My problem was that I had the field on int(10) when I changed it to bigint(20) it solved my problem.

If others are having this problem. Check your field size first. :)
