Logstash continuously crashing..

This looks like split brain. Have you tried powering down all the nodes and bringing them up (slowly) one at a time?

Can you also send the contents of these files from each machine:

Code: Select all

/usr/local/nagioslogserver/var/cluster_hosts
/usr/local/nagioslogserver/var/cluster_uuid
/usr/local/nagioslogserver/var/node_uuid
