Can you clarify what happens when it "pauses the upload process after certain time"? For instance, do you get any error/output?

 

Also when you say you upload a "large number of photos/files", how many are you uploading simultaneously?

    Greg-DB , we have a system where in we upload almost 100-150 images/files at a time. 

    With regards to error message, we sometimes get upload timeout from dropbox and sometimes it just pauses without going to error block.

    So not really sure what is causing the issue. dropbox sdk has mentioned in the documentation that iOS wont stop the upload/download process and there is no timeout.

      Uploading 100-150 files at the same may exhaust the system or network connection, as each one requires its own HTTPS request. I recommend limiting how many you perform simultaneously. You may want to experiment a bit to see what a good limit is for your scenario/environment.

        Hi Greg-DB , I tested the app several times.

        As per my investigation the issue is it goes into error block for few upload requires(out of all) with timeout error when trying to upload so many files in a loop at once.

        Is there any solution provide by Dropbox SDK for this other than limiting the number of files/requests to upload at a time?

        Let me know soon.

        Thanks,
