6 years ago The fix is to have unique test file names. The test downloads are very small, so only an application is fast enough to generate overlapping requests, therefore we can rotate a limited number of test files names.
twc has its own backup mechanism, and generates a 'save' and 'backup' download requests are the same time. savetiddlers responds by generating 2 test downloads, but these have the same name/path and this causes one of the download to stall (you cannot mix 2 downloads into one target).
