Here is the old issue: Error Messages in Logstash Logfile io.netty.channel

Hi,

I am recieving the following errors in my logstash log file on the instance on a regular basis:

[2020-09-15T02:00:17,587][WARN ][io.netty.channel.DefaultChannelPipeline][main][localinstance] An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.
