Graylog 2.4 cluster setup not stable

[groovyghost (Rahul)]

Incident :
In our test environment cluster setup there aree 3 nodes with graylog,mongod, elasticsearch installedd in all 3 nodes.mongod is running in replica set. In web ui only one node (3rd node) is showing and other nodes sometimes pop up with “unable to load throughput” and goes.

Centos 7
Graylog 2.4.3
ES Version 5.6.0
Mongo 4.2.12

Steps i have already taken :
Tried sync with NTP
Reinstalled Mongodb in one node,though all nodes were showing it wasnt stable and gone in 2 mins

Are you really using those ancient versions fo all the components?
I think, it will be hard to find someone, that is using them…

Just a question, what java version is Graylog running on?
