[spike] find out what type of requests might trigger NodeJS heap/memory errors
Closed, ResolvedPublic
Actions

Description

What/Why:
Last quarter, we noticed frequency of the NodeJS heap/memory, GC-related events in our logs. We have established that this is a regular occurrence and devised tools to track these better via logging and metrics. (https://phabricator.wikimedia.org/T378785). However, we have yet to pin down what/type of requests spur these and then how we might refactor the code to reduce or completely prevent these Nodejs-generated errors entirely.

note: heap memory issues continued investigation and addressed in this ticket and also occur too frequently that leads us to believe they are not exclusive to specific functions.
