Server crashes (failed login from Taiwan)

[Arsimael_]

Hello,

I have a problem: Since a few month, my sc2 Server crashes frequently. The logfile says this:

code:

After this my server breaks down. I blocked all connections to my server from Taiwan with IPtables, but thats not a permanent solution. (I had the same coming from china and Korea). Does anyone know that problem? How can I solve it?
