Cause

Mobility Server tries to download an attachment from the POA, however the speed throughput between the POA and Mobility server is too slow for the chunk size of the attachment causing all the threads to freeze up on that attachment. Applying the fix above reduces the chunk size causing the attachment to reach mobility server in smaller chunks

Additional Information

In the future release, it is planned to make the chunk size a configurable option
