[Bug]: 504 Gateway Error when loading users into FusionAuth Cloud Instance #2750

Closed mooreds closed 3 weeks ago

What happened?

Saw this error intermittently when loading 50k users at a time into a large HA FusionAuth cloud deployment. Usually happened after the 3-4th load

Nothing showed up on the cloud watch monitoring.

This seems like a performance or sizing question? If we exhaust system resources, or db resources such that the load balancer can't service the request, this will happen. But I don't know that it is a bug.

Fair.
