the server just starts late, it takes about 5 minutes, sometimes 10, to start.

Oh. Well, buildcraft is the obvious suspect, seeing as it's the only mod I see mentioned in this log.

This line;

at buildcraft.silicon.TileLaser.findTable(TileLaser.java:160)

makes me guess that for some reason all of the lasers in your world are brute-force-style searching through your worlds for tables to connect to when you start. Are any of the lasers/laser tables doing anything funky?

If it would be okay to do so, you could try deleting them all either from within minecraft starts or with an external tool.

Does the rest of the log look exactly like this? If not, could you post more?

I can't remove all the lasers in the world, players would definitely not be happy.

Don't pay attention to the internal server error, that doesn't usually happen.

Don't pay attention to the internal server error, that doesn't usually happen.

That... Should mean we should pay attention. It doesn't usually happen, and now things are breaking XD.

Anyhow, TheByteMaster is right about it dying trying to find table connections. But not because its brute forcing, I think. The log says its creating the buildcraft fake player, AFTER the entire thing dies... For lack of a better way to say it, the server is running its startup arse backwards. The only other error is towny failing, and I'm not sure if the two are connected.
