Deluge keeps failing downloads to error every few hundred MBs

Hi all! Just this...I have a remote Deluge server I connect to with the Deluge thin client. The Deluge server is connected to all the -arr servers, which add the torrents to download. However a lot of downloads start crapping out every few hundred MBs. They get to speeds of 25MB/s (normal for my current connection), and then shortly after show an error. I do a forced check, and they end up on paused mode. I press play, and after less than ten seconds...error again. It's a PITA to keep slowly pushing forward these torrents. Any idea what causes this, or how to fix it?
