Elastic won't start - Java Heap


(Lowdmt) #1

Hi,

Running ELK 6.4 with x-pack activated (trial licence) on a single Redhat server.

First sign that something was going wrong was Kibana not letting me log in, I got to the logon screen but my password stopped working. I decided to restart the kibana service. From there I found that it was no longer listening on 5601 (connection refused), checked and re-checked my config but still couldn't figure it out...went down a rabbit hole thinking my issue was kibana.

Actually, after some time I realised that elastic wasn't working!

I've pasted my error log below from var/logs/elasticsearch

my jvm.options settings are default.

Xms represents the initial size of total heap space

Xmx represents the maximum size of total heap space

-Xms1g
-Xmx1g

For some reason I can't find the error file: ErrorFile=/var/log/elasticsearch/hs_err_pid%p.log
