Get current stack trace of running node js from outside

Question

I have a node application that periodically spikes to 100% on my production server. I would like to be able to send a signal to the node process that will give me a stack trace so I can find where in the code the problem is. Is there any easy way to do this?

My server is ubuntu 14.04.2 and I'm running node 0.12.2

I was able to get a stack trace by compiling my own version of node and v8: https://github.com/joyent/node/issues/25263
