Disappearing Elasticsearch. Where to find clues?

Elastic Stack Elasticsearch
1

Hi ,
We have been using Elasticsearch for a couple of years and last month Elasticsearch stopped without any reason. We could find no errors in any logs to suggest the cause. Also the were no JVM errors. Our hosting company did some investigating and also came back without any clues. Since then it has happened a further 4 times and we are struggling to try and identify the cause.

Has anybody else experienced this? Do you have any ideas on where we should be looking for clues? Is this the right forum for this question?

Any help would be much appreciated.

Thanks,
Ian

FYI, the status is:

curl -XGET 'localhost:9200'
{
"status" : 200,
"name" : "Blood Rose",
"version" : {
"number" : "1.1.0",
"build_hash" : "2181e113dea80b4a9e31e58e9686658a2d46e363",
"build_timestamp" : "2014-03-25T15:59:51Z",
"build_snapshot" : false,
"lucene_version" : "4.7"
},
"tagline" : "You Know, for Search"
}

It's probably best to start with increasing the logging level to debug and see what happens.

Upgrading would also be a good idea :slight_smile:
