Hello. I´m new with ELK. I have an ELK cluster with the following:

Node1: elasticsearch, logstash, kibana || 32GB RAM || -Xms12g, -Xmx12g  
Node2: elasticsearch, logstash || 32GB RAM || -Xms12g, -Xmx12g  
Node3,4,5: masterdata

When monitoring with Zabbix **Node1** Logstash ports seems to go down after a wile (ports 5043 to 5047). **Node2** its ok.

I see the following on Node1 **/var/log/logstash/logstash-plain.log**

After 5 minutes the ports are up again, but on Node2 this is not happening.

Can you help me with this?.  
Thanks!!
