Odd. I could see your messages when you said them on the server, but they didn't appear in game for /ages/. That would suggest the PC running the server was slowing up, but the server was only using 400 meg of RAM and CPU usage never went over about 60%.
My router looks like it might have been going a bit crazy, though. Showing only 2% of RAM available :S
THink it could be my router... or my PC. Or the fact that this is all done in fucking Java :@
Router says:
Load Average
17%
0.23, 0.17, 0.10
Might give it a reboot just for the hell of it.
