node-webkit-agent wont connect to my application

Question

I've been trying to debug my node application as I keep getting 'stack size exceeded' errors. I've replaced global accidental vars with the prefix var for declaration but I can't seem to figure out what the problem is. I tried using node-inspector but apparently the profiling tab is not available anymore. I tried finding other methods of analyzing my garbage collection with heap analysis tools but they all seem to be paid services that I can't really afford just for a grad school project.

I tried using node-webkit-agent but I am not able to connect to the agent. After running my file, node myFile.js and entering kill -USR2 (pid of myFile), whenever I restart my app again I get the following error:

I don't really know why this is happening... I'm running it on a free EC2 instance and have gotten node-inspector to work previously but as mentioned its not helping me to debug memory leaks. I think I may start setting up node-memwatch as I'm not really sure why this is so hard to get working and am not really very optimistic about using open source free tools with a GUI for memory usage for nodeJS.

Any help would be greatly appreciated!!
