Hello, Same issue as with the other user's thread: > [@Logstash 6.1 Fatal error crashing background running logstash when stdout output plugin is used](https://discuss.elastic.co/t/logstash-6-1-fatal-error-crashing-background-running-logstash-when-stdout-output-plugin-is-used/114586): > > Hi Team, I'm getting this error while receiving data via the input plugin if stdout output plugin is used when logstash instance has been put to run in the background. It is not a problem per se as I do not intend to use the stdout plugin when logstash is intended to be run in the background. However I do not recall this happening before so was wondering if this is a "new" thing.
