Hi there,

I'm currently running Logstash on Kubernetes and have configured a pipeline with a Persistent Queue and the setting `queue.drain: true`. In this setup, I'm curious about Logstash's behavior when it receives a SIGTERM signal and encounters a scenario where the output is unavailable.

Specifically, does Logstash indefinitely wait to drain the queue, risking ungraceful termination, or does it detect the output failure and proceed with the shutdown, leaving messages queued?

Thank you.
