Native ImportCSV Bug?

[JMPeterson]

Running into an interesting bug lately. We use the native ImportCSV function, and are starting to see duplicate entries in the database for a single import.

I have not been able to see duplicate runs in the logs, but the DB clearly shows the same rows being imported at least twice. The only difference I can see between the rows of data, are the timestamps. Normally there is a small fraction of a second difference between the imported rows (see orange highlighted), but in this case its like the import function is being engaged multiple times in a second.

The users can not act fast enough to hit the import button, clear the pop-up and re-engage the import process in the four tenths of a second discrepancy between these entries. And there are only a dozen rows on the import, which would be processed almost immediately. Does the CSV import have an auto-retry function like a bot? Are we somehow sending the same data down two separate data-streams simultaneously?

Has anyone else seen any odd behavior with CSV imports?
