Julian Feinauer created PLC4X-127:
-------------------------------------

             Summary: Uncaught exceptions from the Netty Pipeline
                 Key: PLC4X-127
                 URL: https://issues.apache.org/jira/browse/PLC4X-127
             Project: Apache PLC4X
          Issue Type: Bug
    Affects Versions: 0.3.1, 0.4.0
            Reporter: Julian Feinauer


When using in production for long times.. we often times get this WARN from Netty.
This should be adressed and handled properly.

{code:java}
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.
