Server running on 3.3.9. I start a download of a 175M multimedia file with firefox, about 5 seconds later, I restarted the web server gracefully via the GUI. And then about 15 seconds later, the download "finishes" (firefox progress bar says 100% done) but the file is partially downloaded only. I tested it on other multimedia files too and the same thing happens. Now, I know why every time I gracefully restart the server, the overal outgoing speed decreases shortly afterwards. Hope you can find a fix soon.
