Running as a service on Linux
Checking the ElasticSearch logs, es.log, I find these warnings:
WARN es[o.e.b.BootstrapChecks] max file descriptors  for elasticsearch process is too low, increase to at least  WARN es[o.e.b.BootstrapChecks] max virtual memory areas vm.max_map_count  is too low, increase to at least 
These settings seem to be easily configurable, already documented here: https://www.elastic.co/guide/en/elasticsearch/reference/current/system-config.html
I think settings these values should be documented in the Sonar install guide, somewhere around here : https://docs.sonarqube.org/display/SONAR/Installing+the+Server What do you think?
Thanks and cheers,
I also have
ActiveRulesPublisher issue described in: Initial setup integration failing . Still need to try the suggested fix. I have the feeling not having the warnings to begin with will help to avoid this issue in the future.
