To get in sync with the rest of the production and general improvements, we need to upgrade to 4.2 or later nodejs
We should probably do it one server at a time - e.g. migrate maps2004 first, test, and migrate the rest. At this point, any one server is capable of handling all of the maps traffic.
Older reasons:
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.
(node) warning: Recursive process.nextTick detected. This will break in the next version of node. Please use setImmediate for recursive deferral.
