I am getting an error: "SystemCallError: Unknown error (SystemCallError) - No message available"

This is from the TCP Output: [https://github.com/logstash-plugins/logstash-output-tcp/blob/master/lib/logstash/outputs/tcp.rb#L152-L160](https://github.com/logstash-plugins/logstash-output-tcp/blob/master/lib/logstash/outputs/tcp.rb#L152-L160)

I don't know how to resolve this issue.

This appeared to be an issue with our upstream consumer.
