The port used in the test is determined by the unused_port method. However, since the protocols are not properly specified, they wll look at free TCP ports. https://github.com/search?q=repo%3Afluent%2Ffluentd%20unused_port&type=code At least,...

Hmm, I have tried to reproduce https://github.com/fluent/fluentd-kubernetes-daemonset/issues/1573, however, I can't reproduce yet. @der Can you provide the more information how to reproduce that ?

If the issue still occurs in your environment, please report the steps to reproduce it.

Can you send a Pull Request?
