Project throwing 500 UI error

I have a project that, for some commits, is throwing a 500 “something went wrong”. I notice, watching a “top” on the instance, that “git” spins up and runs hard for a while before the 500 error. I’m wondering if anyone could tell me where to look for any clues in the logs…

I’m currently running 13.9.2-ee core on Ubuntu 18.04 LTS as an AWS instance. Omnibus install, since instance.

Bump… anyone have any sort of advice? Thanks.
