## TL;DR

If the LaunchDarkly stream keeps multiplying reconnect attempts, upgrade the node server SDK to 9.4.3 or newer.

## Steps

1. If the LaunchDarkly stream keeps multiplying reconnect attempts, upgrade the node server SDK to 9.4.3 or newer. The bundled launchdarkly-eventsource library could emit one error multiple times per request, triggering duplicate reconnects; the reporter confirmed preliminary tests looked good after upgrading.
