nginx: how do I track down a random 500 from nginx (not my application). Potentially has something to do with load?

500-error

We recently had some 500's from nginx itself that somehow were not logged (we have screenshots, but nothing in the logs). That is weird in itself, because usually errors show up there. Regardless, I am wondering if there is something like a connection pool size that if maxed out would result in a 500? We have correlated it potentially to a recent spike in traffic, but it is not conclusive.

Anyone have any ideas of how to begin to approach such an issue?

I have a nginx with geoip, but it is not working rightly.
