And when it's happening, all I need to do is restart the queue. What could be causing it?
I'm running on 64-bit Fedora 12, using a Buffalo WHR-G125 Wireless Router.
Your host might have the max number of connections maxed out. I had this problem once while uploading some files to hostgator. I was troubled because I was up and running on day then next day queue kept stopping. Some guy was uploading a ton of stuff and using up all the connections so i had to adjust my number of connections to one to squeak in there to get my stuff done.
