Logstash 6.4.2 stopped processing after 45 days.. But the status of logstash shows still active and running. After restarting that, it started receiving the logs from Filebeat 6.4.2 version. We have persistent queues in place. This is a production system, so there is no limitations on space, memory and cpu..
Not much of any useful logs also. Did anyone face similar issue? This raises a concern of reliability..
