Suddenly getting errors like "End of Stream", "recv failed", etc on SMP

[mjmr89]

I've been playing on a server for a little over a week now, and this morning while playing it started to disconnect me and send me to an error page saying things like "End of Stream", "Connection Lost: Internal Exception: java.io.IOException: Not Enough Data", etc after around 3 minutes of play. I can relog, but it will just happen again in a few minutes. It also has invisible/missing chunks most of the time. If I need to post any more info to help, please tell me and I'll get it. Thanks!

EDIT: Another message is "Connection Lost: Internal Exception: java.net.SocketException:Software caused connection abort: recv failure". This one is from another server, after just a couple of minutes, so I doubt its a server-specific problem.
