seems that you have "versioning" enabled on mysql 3.23.x

cited from the TYPO3 3.7.0 release notes:

" There are two warnings about this release:
- DO NOT use the new "version" extension if you are running a MySQL version
below 4.0.18! If you do a bug in MySQL will mess up the "Next Autoindex" of
tables in the database meaning that unique IDs are raised to nearly 2
billion and you will get a lot of trouble. This is NOT a bug in the
versioning extension, but a problem with MySQL which seemingly is fixed in
versions only above 4.0.18 "
