Hello, When I run "/usr/share/elasticsearch/bin/elasticsearch --version" I get the following Java error: Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit\_memory(0x0000000614cc0000, 7167279104, 0) failed; error='Cannot allocate memory' (errno=12) # # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (mmap) failed to map 7167279104 bytes for committing reserved memory But if I cd to the directory and run: ./elasticsearch --version if works fine with no Java errors Is Java expecting 7167279104 (7GB) of free memory to map? System Stats: Centos version CentOS Linux release 7.6.1810 (Core) Elastic version 6.7.1 VM: 4 cores 16GB RAM 600MB free ---

It's not the system memory it is the JVM in the configuration.yml that you need to configure. ---
