java - Elasticsearch memory probles -

when i'm trying start elasticsearch in ubuntu startup script gives me next error:

java hotspot(tm) client vm warning: info: os::commit_memory(0x74800000, 201326592, 0) failed; error='cannot allocate memory' (errno=12) # # there insufficient memory java runtime environment continue. # native memory allocation (malloc) failed allocate 201326592 bytes committing reserved memory.

i seek search , couldn't find solution this. if restart machine work day , elasticsearch goes downwards , appear error.

i setup property bootstrap.mlockall: true in elasticsearch.yml file, , properties in default elasticsearch file:

es_heap_size=512 (i have 1gb of ram) max_locked_memory=unlimited

someone know need do?

thanks
