I have setup Elastic APM which sends data to Elasticsearch.  
When I setup Elasticsearch with single instance, Elastic APM server working fine responding 202 response.  
When I setup Elasticsearch cluster(3 master, 3 data nodes, 2 ingest, 2 coordinate nodes) , APM server server misbehaves responding interleaved 202 and 503  
Using coordinate host in Elastic APM  
This link [https://www.elastic.co/guide/en/apm/server/master/common-problems.html#queue-full](https://www.elastic.co/guide/en/apm/server/master/common-problems.html#queue-full) has some info but I am unable to resolve issue.
