Hi there,
@accesstomemory
What version of AtoM are you using? Are you installed on Ubuntu 14.04 or 16.04, or have you made other changes in your installation environment? Did you already have AtoM installed and running, or are you receiving this error during your initial installation? Is AtoM working otherwise, or is the search index completely down? What version of Elasticsearch do you currently have installed?
In the meantime, here are some initial thoughts:
It may be as simple as restarting Elasticsearch. You can also check the status of the service, which might provide more information.
On Ubuntu 14.04:
- Check status with:
- sudo service elasticsearch status
- Restart ES with:
- sudo service elasticsearch restart
On Ubuntu 16.04:
- Check status with:
- sudo systemctl status elasticsearch
- Restart ES with:
- sudo systemctl restart elasticsearch
- /var/log/elasticsearch/elasticsearch.log
In some cases, errors can happen if the Java runtime environment and/or the ES heap size doesn't have enough memory. The size of the heap is declared in /etc/default/elasticsearch - - specifically the ES_HEAP_SIZE for your install. So you could try changing this value - for example, you could change the heap size value to "2g" if you have two GB of memory available. Once the value is changed you have to restart Elasticsearch.
There are more details for AtoM 2.4 and earlier / ES 1.7 here: https://www.elastic.co/guide/en/elasticsearch/guide/1.x/heap-sizing.html
Here is some other general ES configuration documentation that might be handy:
Of course, to assign more memory to ES, you need to have more memory available on your server. AtoM can run on as little as 2GB of memory for a medium-sized installation, but we generally recommend at least 4GB if possible - especially during installation and configuration, as ES requires a lot of memory during the installation process. If you are able to add more memory, you may also need to adjust some of the memory limits in your PHP configuration file. See:
Let us know what you find!
Cheers,

elasticsearch version 5.6.16

Hi again,
AtoM 2.4.1 and earlier require Elasticsearch 1.7 to work as expected. We have upgraded ES to version 5.6 in the upcoming 2.5 release, but this version has not yet been finalized. We are hoping to have 2.5 publicly available in late May or June 2019.
For now, you will need to downgrade to an earlier version of Elasticsearch. See the Elasticsearch installation instructions for AtoM on Ubuntu here:
We no longer maintain documentation for using Apache with AtoM - our preferred webserver, which we use in development, testing, and production is Nginx. In light of this, the amount of support we are able to offer for resolving Apache issues is limited. However, we know there are many Apache users in our community, so I hope that perhaps another forum user might be able offer some insight.
I can't guarantee that they will work with later versions of AtoM, but you can look at the older 2.2 docs for some ideas about how to configure your Apache server:
We've also been trying to tag posts in the forum to make searching easier - you can read more about how to use the forum tags on our wiki here.
This link will show all posts tagged with "Apache" from the last couple of years:
You might find other useful suggestions in some of these threads.
