When I'm trying too start the elasticsearch in my Ubuntu the startup script gives me the following error:
Java HotSpot(TM) Client VM warning: INFO: os::commit_memory(0x74800000, 201326592, 0) failed; error='Cannot allocate memory' (errno=12) # # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (malloc) failed to allocate 201326592 bytes for committing reserved memory. I try already to search by this and I couldn't find the solution for this. If I restart the machine everything work well for a day and then the elasticsearch goes down and appear this error.
I already setup the property bootstrap.mlockall: true in the elasticsearch.yml file, and also the properties in the default elasticsearch file:
ES_HEAP_SIZE=512 (I have 1GB of RAM) MAX_LOCKED_MEMORY=unlimited Someone know what I need to do?
Thanks

The Elasticsearch process is very memory intensive. Elasticsearch uses a JVM (Java Virtual Machine), and close to 50% of the memory available on a node should be allocated to JVM. The JVM machine uses memory because the Lucene process needs to know where to look for index values on disk.
As a Java application, Elasticsearch requires some logical memory (heap) allocation from the system's physical memory. This should be up to half of the physical RAM, capping at 32GB.
You have configured a virtual machine with 1 GB of RAM, but elastic is trying to start with 2 GB of RAM (default for Elasticsearch version 5.X)
Either give more memory to your VM, or change Elasticsearch JVM settings /etc/elasticsearch/jvm.options and lower the values of the following parameters: -Xms512m -Xmx512m
