User uploading here (https://www.synapse.org/#!Synapse:syn9874666) - large files of ~200GB each from an institutional cluster.
Getting THOUSANDS of warnings:
“The presigned upload URL has expired. Restarting upload...”
Advised user that with large files, warnings are expected but should not affect performance.
Engineers on the users's side are investigating to check on performance, will post any followup here.
