Summary: Here's a series of badness that easily leads to a crash, in reverse order: - Lodash's map() function interprets an object with a .length property as an array. - Some very old code generated human-friendly descriptions of user actions, applying map() to parts of them. It so happens that this generated description isn't even used. - If a user action is encountered with a sufficiently large length propery, map() would exhaust the server memory. Fixed by removing old unneeded code, and replacing some other occurrences of lodash's map() with native equivalents. Test Plan: Tested manually on a local reproduction of the issue.
