The Logstash Collector keeps stopping and will not start after I restart it.

Is this a new install or has it been running and just started crashing/failing to start?

The first place I would check would be /var/log/logstash/logstash.log and /var/log/elasticsearch/<cluster_id>.log:
Run both of these and try restarting the service and gather any messages that pop up as a result.

I'll bet five craft beers that it's memory related.

Now you're speaking my language : )

eloyd has a good point and those are usually pretty easy to see in the logs. How much total memory is on the system?

Thanks, my fault, should have checked that first. Found a few of the ports wouldn't open properly. Fixed that and it's working.

Glad to hear you were able to resolve it with the logs!

Eloyd... looking forward to the beer selection : )
