I'm playing on a SMP server which is quite old. There are many chunks from many different versions of minecraft. Most were generated with a bukkit modded server jar, but with only dynmap installed - so no significant changes (any?) to vanilla map-gen mechanics except as released from Mojang.
Now, whenever exploring new areas (new biomes anyone?) every few seconds everyone experiences a timeout error and must re-connect. The server didn't go down, evidenced by all mobs and entities being identical to before disconnect.
The question is: is the server simply under-powered for new chunk generation and we are all disconnecting because the server isn't sending keep-alives often enough? Is anyone else experiencing the problem? And, finally, is dumping more memory enough, or do I need a new mobo/processor?
