Rate Limiting Sentry-Ruby 4.1.5

I am having an odd rate limiting issue. I traced it back to Feb 07 when I upgraded sentry-raven 3.1.1 → sentry-ruby 4.1.5. I am seeing the following log entries repeated many times per minute. Nothing in the log entries or before/after that would seem to tell me why. Submitted a request to Sentry to investigate. Awaiting a response. Anyone experience this or know what is causing it?

My sentry.rb
Sentry.init do |config|
config.dsn = ‘’
config.enabled_environments = %w(production)
config.traces_sample_rate = 0.75
end

Log Entry repeated…
