Description
I'm trying to cache errors on connect to a redis instance both by using
ok, err = ....
and wrapping up the code with a pcall
In both cases still an error line goes to nginx error log. I have a high load application and if a redis instance goes down for a few secs my error log gets flooded with messages. Is there a way around it?

Research direction
No source file or test is identified in the issue. Start by reproducing a Redis connection failure with both ok, err handling and pcall, then trace why the failure reaches the nginx error log; done means establishing a supported way to suppress expected connection errors without hiding returned failures.
