I have installed Elasticsearch on my Digital Ocean Plesk server to work with Active Collab. It all seems fine apart from after a few seconds it seems to stop.
Trying to keep the Elasticsearch nodes alive but it keeps stopping, every damn time. Any advice on this ☹
- I try: `sudo service elasticsearch start`
- then: `curl -X GET "localhost:9200/"`
I get a response, but only briefly, then it stops and I get the message:
`no alive nodes found in cluster` in Active Collab

There should be some information about what's going on in the Elasticsearch server logs. Can you share them here?

Hi @DavidTurner.
Thanks for the help. I have a few logs listed in the directory, is there any particular ones you need?

Yes, the contents of `elasticsearch.log` would be very helpful. I think they'll be too large to post inline but can you share them as a [Gist](https://gist.github.com)?

Thanks, that looks kinda normal except it's much slower than usual, and I wouldn't expect GC warnings in a cluster with no indices. What are the specs of the host machine (RAM, CPU, etc)? Also it doesn't look like the node shut down cleanly. Does `dmesg` indicate it was terminated by the kernel (e.g. the OOM killer)?
Have you [set the heap size to less than 50% of the total RAM](https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html)? Have you [disabled swap](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-configuration-memory.html)?
