Spring RTS Engine

About 10 mins into a game Spring crashed and it gave the error.

Fatal Error
Error receiving data from socket: Unknown error

I thought it might be a one off, so I tried again and I got the error again probably about the same amount of time into the game...

Anyone know what's triggering this?

Happened to me when i had a flaky internet connection, but this was a few spring releases back.
Anything in the infolog?

nah, this only happened twice when I posted this thread, hasn't happened since.
