Running 
osc service remoterun
osc service wait
on openSUSE.org home:eeich:ohpc:upstream_test/pdtoolkit keeps failing for me (4
attempts).
Doing the same on a local checked out repo succeeds (after a long time).
It is possible that the download of the tar-archive  containing the package
sources fails (the download_files service). This is not really clear from the
error message as it is not really telling:
eich@sles12:/space/obs/home:eeich:ohpc:upstream_test/pdtoolkit> osc service

^[[CServer returned an error: HTTP Error 502: Bad Gateway
