Elasticsearch failed to start on Ubuntu 18.04

Sebastian_F · March 24, 2021, 8:00pm

Hi folks,

I am an elastic noob and I am stuck with running elasticsearch on an Ubuntu 18.04 V-Server with 4 Cores, 8Gb Ram and a 100GB Hard drive. I followed the instructions from this post: Installieren und Konfigurieren von Elasticsearch unter Ubuntu 18.04 | DigitalOcean and I end up with the following error:

The errors says OutOfMemory, but it should be fine with 8GB?
If anyone could help me, would be awesome..

Kind regards!

Welcome to our community!

Please don't post pictures of text, they are difficult to read, impossible to search and replicate (if it's code), and some people may not be even able to see them

Ah sorry my bad.
So after using the command systemctl status elasticsearch.service I get the following error log:

Did you change the memory options? If so, check that you don't use more than 4gb of HEAP and that this memory is available on your machine (meaning that no other service is running).

Sebastian_F · March 25, 2021, 6:33am

Hi David, I kept the elastic default config. My machine has about 7.9GB RAM free

dadoonet · March 25, 2021, 6:44am

What is the free memory available and which version are you running ?

Sebastian_F · March 25, 2021, 7:46am

I have about 94Gb free disk spaces. My elastic version is 7.12.0:
root@h2920142:/usr/share/elasticsearch# bin/elasticsearch --version Version: 7.12.0, Build: default/deb/78722783c38caa25a70982b5b042074cde5d3b3a/2021-03-18T06:17:15.410153305Z, JVM: 15.0.1

dadoonet · March 25, 2021, 7:52am

I'm asking about the free RAM memory not the free disk size.

Sebastian_F · March 25, 2021, 7:54am

ah ok, ye I told that in the previous post. Its 7.9GB

Sebastian_F · March 25, 2021, 7:56am

using free -m

Could you try change the JVM memory settings?
In 7.12 elasticsearch tries to guess this value for you but may be there's something wrong here.

You should rarely need to change Java Virtual Machine (JVM) options. Elasticsearch includes default JVM options that work well for most production environments. If needed, you can override these default options using jvm.options files or the ES_JAVA_OPTS environment variable.

See Setting JVM options | Elasticsearch Guide [8.11] | Elastic and Advanced configuration | Elasticsearch Guide [8.11] | Elastic

Try with something like -Xmx1g -Xms1g to start with.

Also do you see any elasticsearch logs?

Sebastian_F · March 25, 2021, 9:35am

I have created a jvm.options file under the jvm.options.d folder and added the line -Xmx1g -Xms1g. Is this correct?
I have the same error still.
My logs look like this: tail -f /var/log/elasticsearch/elasticsearch.log:

Could use the markdown format for code and logs? Instead of <code>?
I edited your post so you can see how this should be done.

Could you share the full /var/log/elasticsearch/elasticsearch.log?

Sebastian_F · March 25, 2021, 10:32am

ah sorry, yes I ll try the markdown

This could be your problem
max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

Try increasing it and that should help.

If you don't use it, I'd disable machine learning.
But I feel like there's a bug. I'm checking a bit more.

How much did you set to the heap? Apparently it's using 4gb.

Sebastian_F · March 31, 2021, 5:22pm

I tried to raise the memory but it had no impact on the error
