Out of range value for column 'index_id'

updating or inserting a new record in providence I get the following error:

Out of range value for column 'index_id' at row 1 in /var/www/providence/app/lib/Db/mysqli.php line 316:

In Db_mysqli->execute(Object DbStatement, Object DbStatement, ' INSERT INTO ca_sql_search_word_index (table_num, row_id, field_table_num, field_num, field_container_id, field_row_id, word_id, boost, access, rel_type_id) VALUES (57, 222260, 50, 'COUNT', NULL, 0, 8, 1, 0, 0)', Array(0), ) in DbStatement line 151

index.Id in table ca_sql_search_word_index is defined as int(10) , maximal value of int in mysql is 4294967295.

BUT:

SELECT `AUTO_INCREMENT` FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = 'raubgut' AND TABLE_NAME = 'ca_sql_search_word_index'

shows 4294971152 => out of range.

Any idea what to do?
