Probably only a problem on Vertrauen, but some QWKnet nodes, for some unknown reason, like to FTP-connect multiple times concurrently and request to download a QWK packet. This creates a race condition where the QWK packet gets created/downloaded/deleted before the second FTP connection can successfully download the same file, thus logging an error "opening file " on the server (VERT). So if the pack*.now file already exists, reject the download request. "What are doing?" is what I really want to ask these nodes, but better just throw them an error response and quietly move on.
