I have seen quite a lot of log level errors popping up in our application with the following message:

ERROR -- ddtrace: [ddtrace] (/usr/local/bundle/gems/ddtrace-0.32.0/lib/ddtrace/workers.rb:58:in `rescue in callback_traces') Error during traces flush: dropped 4 items. Cause: undefined method `update' for #<Datadog::RateSampler:0x000055baf400c530>

I went through the code in this repo and can confirm the rescue block but I couldn't determine why dd_trace was throwing an undefined method update for a RateSampler instance.

Is this a known issue?
