Known Issues

Uploading files

• Parallel uploads will fail if they are started after a large file has already started uploading.

  • Behaviour:

    • Even small files begun while a large file is uploading will fail if it is more than 2 minutes before the large file finishes. The files will appear to succeed (the bar will reach 100%) but when the first file completes, the subsequent files will switch and be shown as failed.

    • This is a limitation of the InvenioRDM file uploading infrastructure and will take significant time to fix (not a current priority).

    • It should only happen if the first file takes longer than 2 minutes to upload. (Around 200mb on a fast connection.)

  • Cause:

    • Although the PUT requests to send the file content are made in parallel, the requests are processed by InvenioRDM sequentially in a queue. This can leave some upload requests waiting a long time for a response if they are queued behind a large file upload. If this wait time exceeds 2 minutes, the load balancer will cut off the idle connection causing the upload to fail.

  • Workaround:

    • wait for large files to finish uploading before starting other uploads.

    • if an upload does fail, click the trash icon to remove it and try that file again on its own.
