Ah, that sounds helpful.
I set the logging levels to trace, and yes. I can see "com.esotericsoftware.kryo.SerializationException: Buffer limit exceeded writing object of type..." at com.esotericsoftware.kryo.Kryo.writeClassAndObject(Kryo.java:483) now.
I tried to set larger bufferSizes for server and client (32768, 16384). It helped, but it also increased the latency terribly. Or maybe not the latency because the whole game is getting frozen every second or two.
EDIT : ah, nevermind, that was caused by large amount of logging output. So it seems to be working.
Are there some recommanded values ? Or is there some approach I can take to this ? I can set the values higher, but still, it may happen, that they will overflow. Is there some solution to this situation ?
