The file uploading problems are due to an emergency change that David Anderson made in the BOINC client a couple of months ago when SETI BOINC was having trouble with its servers. Unknown to me, he modified the client so that if the upload file size is less than one megabyte, the client always tries to upload the file starting from the begining, rather than doing partial uploads.
If one of these uploads failed, then the next attempt would cause problems on the server side.
After some discussion, David has reverted this change: future clients won't suffer from this problem.
As a temporary workaround for people using current clients, I have modified the Einstein@Home server-side upload code to eliminate the failure mode.
People with slow connections who have trouble completing uploads should upgrade their BOINC client as soon as a new release comes out. 5.2.13 is flawed in its handling of file uploads.
