> As part of https://issues.jboss.org/browse/SWSQE-113 the command "sudo sysctl -w vm.max_map_count=262144 " was executed on the B12 cluster in order to allow ElasticSearch to run correctly.
> However I tried to run a performance test this morning and the ES deployment failed with 
> ERROR: [1] bootstrap checks failed
> [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
> Can you reapply this and do whatever is needed to make sure it persists over cluster rebuilds or restarts?  Thanks.
