Screen recording metadata missing in Performance Dashboard during JMeter load test

Screen recording module fails to register metrics when initial WebSocket handshake payload lacks specific metadata tags.

yaml
metadata:
 tags:
 - load_test_run
 - org_id: 12345

In recent JMeter tests with 50 concurrent users, similar zombie processes appeared. The recordingId is generated, but no data flows to the dashboard after 2 minutes. Is there a capacity limit for metadata ingestion per edge node? Running GC version 2023-10.
