Batch move operation fails due to internal error

Hi,

I am currently working on an server-side application that is handling large quantity of image files using Dropbox. The application is using Java SDK to interact with Dropbox API. During our workflow, we have to move a large number of folders from one location to another in Dropbox. The number of folders in each such request varies between 500-1000 where each of these folders holds 6-8 high quality images. I am using batch-move operation for moving these folders. While the operation is performed successfully most of the times, occasionally it failes citing internal error. The problem is when it fails, it deletes the folders from the source path but does not copies them to the target location which is resulting in loss of files.

Any help would be appreciated as to why this is happening and what can be done to avoid such situation.

Thank you!
