Hi,
I'm having trouble starting elastic on CentOS via the elasticsearch-service.
I get the error "Could not reserve enough space for the object heap"
I must say that I'm using a pretty low memory VPS, but I think that I
should be able to run elastic anyway.
for reference: the contents of my elasticsearch.conf:
set.default.ES_HOME=/opt/elasticsearch/elasticsearch-0.19.3
set.default.ES_HEAP_SIZE=256
set.default.ES_MIN_MEM=%ES_HEAP_SIZE%
set.default.ES_MAX_MEM=%ES_HEAP_SIZE%
