The umbrella application we’ve been working on for quite some time just started dumping OTP reports.
Application.get_env(:logger, :handle_otp_reports) == false
Is it possible one of our dependencies is injecting them now?
It’s an overwhelming amount of logs 
You can tell Logger
to handle otp_reports and sasl logs with the configuration here: https://hexdocs.pm/logger/Logger.html#module-error-logger-configuration
In this case you actually want to set these values to true. That way Logger handles them and you can disable or quiet them based on log level.

Thanks! We found the problem was that sasl_logs: false had been stripped accidentally.
It appears that this enables otp reports – which I wouldn’t have imagined, but alas
