Research direction

Start with the RemoteWriter warning named in the report and trace how the Java tracer's buffer is configured when dd-trace-java is injected through the Helm chart. Check the reported 1.49.0 behavior against 1.19.0 and identify whether a documented buffer setting or reproducible configuration exists; done requires a confirmed cause and clear configuration or fix.

Bug Report

Recently I've updated the dd-trace-java from 1.19.0 to 1.49.0 and seem to getting pretty frequently this warning

WARN datadog.trace.agent.common.writer.RemoteWriter - Dropped due to a buffer overflow: [1 spans] (Will not log warnings for 1 minute)

Is there a way that I can increase the buffer so I don't miss out logs?

I'm use datadog agent using helm chart and have the dd-trace-java injected in the pods.

Expected Behavior

Possible way to not have dropped spans. Maybe a way to configure the buffer size.
