I have began getting weird stack overflow errors in tilerator, but switching to node 0.12 seems to have fixed them. The warning is repeated hundreds of times, and than it crashes. I am unable to get any stacktrace to figure out what's going on. There has been suggestions on the web to try the code on later node to get a stacktrace. Regardless, node has recently released v4, and even though we cannot yet switch directly to it (i'm getting mapnik compilation errors), we should start planning the migration while the service is not heavily used.
```
