Thanks for the report.
It seems a typo here:

fluentd/lib/fluent/compat/output.rb

Line 368 in c18015c

@counters_monitor.synchronize{ @emit_records += es_size }

Here is a patch: #1164
Could you try it?

[stevenc81]

Thanks for the prompt fix @repeatedly :) I've fallback to version v0.12 as it seems we have some more compatibility issues with v0.14? Sorry to digress, here is another interesting one that only happens in v0.14

awslabs/aws-fluent-plugin-kinesis#80

it seems we have some more compatibility issues with v0.14?

Compatibility layer should work but we don't test all plugins. So it may hit a bug.
