InfluxDB output plugin errors

I seem to get ruby buffer.rb errors of some sort and Nil Exeptions with the influxdb-logstash-output plugin:

`
logstash.outputs.influxdb - Non recoverable exception while writing to InfluxDB exception => Nil 5/21/2017 12:50:30 AM22:50:30.640 [Ruby-0-Thread-22: /usr/share/logstash/vendor/bundle/jruby/1.9/gems/stud-0.0.22/lib/stud/buffer.rb:92] WARN logstash.outputs.influxdb - Non recoverable exception while writing to InfluxDB {:exception=>nil}`

My same configuration works in **other environments** just not production where we have tens of thousands of events per minute. I have allowed unlimited connections, etc, in the HTTP configuration for InfluxDB, and have a flush_size of 1000. Would anyone happen to know what is causing this?
Additional notes - I attempted enabling write-tracing in influxdb's HTTP configuration section, and I do see the events reaching Influxdb. Just nothing shows up in the Database / Measurement in the UI. I confirmed the right retention policy is being used as well. Any help is appreciated. Thanks!
