I have a 128GB RAM server with dual xenons (24 threads). It's running an Ubuntu server.

Whenever I run the map rendering, CPU spikes from ~20% for 93%. When the rendering finishes, the CPU seems to be stuck in 80%, at least in top -c. On matter, top -c shows 50% CPU usage after the command has been typed, and then raises back to 80%.

My world is size is 6000x6000 (3000 radius), if that matters.

This has caused slight headache for me and the hoster, and the only way to get around this is to reboot the whole node.

Here's my settings.py: http://pastebin.com/wyc9xGyz

I've tried with multicore proc at 1 too. No luck.
