streamer.cgi did not close the file handles used for reading files from the rapid pool. This made it send invalid data after more than 1024 files where opened. As streamer.cgi is closed after each transfer this resource leak was difficult to find.
So to download a game with more than 1024 files in the rapid pool needed multiple tries to succeed as a download usually was aborted by the client when it failed with corrupted data. Some older clients even didn't notice the corruption.
Basically only new players hit this bug because updates via rapid requires to download only the changed files which usually are less than 1024 files.
All rapid clients were affected by this bug.
Thanks go to the persistent bug reporters!
