Bulk Import aborts due to inactivity

Hello,

When using the bulk import utility imports are failing midway through due to 180 seconds of inactivity. This only seems to happen when users are trying to upload more than 30 documents, and the first 30 are still uploaded even though the process never completes. Is there any reason you know of that may cause the import to become inactive mid way through the process?

Kind regards,

Catherine
