The same thing just happened to me as well. I am using winston-logsene library which has flat as a dependency. It mostly happens on app regular error where I am dumping a whole object. It certainly shouldn't be causing such wild crash, but I will surely limit on what I am going to be passing in there.

Does anyone have steps to reproduce this issue? Without a reproducible test case there is very little we can do to fix this problem.
