That's what is so maddening. It can work PERFECTLY for days, then sometimes it will hang several times in one day. Change some setting, think you fixed it, bang, it hangs. Change another setting, works great for a while, then it doesn't. Restarting the docker every hour ensures everything works smoothly, and I've never seen a restart munge a download, so it's a great solution if the real issue doesn't get handled. I've had mine on autorestart for several months now, time flies, it may be as much as a year.
