Number of items created have a limit?

Items are created incorrectly after reaching like 2000 records. When a new record is created, it will insert the data into a randomly selected existing record. This is very weird. Is there a limit on how many records can be created? Or where to set the limit?

Thanks,

There's no limit at or anywhere near 2,000 records. There's some eventual limit based on the maximum ID number but that's in the billions.
