CSV import hangs up

Is there something that would cause the CSV record import function to show the spinning circle, but not progress through the import? I have one module that has been doing this - others have not. I’m using my superuser account to do the upload, so permissions shouldn’t be a problem (should they?).

Any ideas?

Any errors in server logs, network requests or other stuff? Its impossible to tell without more information.

It appears that the problem had something to do with a user field in the records. Fortunately, the userID was the same for all the records, so I was able to drop the field in the CSV, import the records, then bulk edit to add the userID. You may want to investigate this, though.
