Solutions

Setting the parameter -Xms to the same value of -Xmx in /etc/elasticsearch/jvm.options solved the problem 🙂 Thanks

export ES_HEAP_SIZE=2024m
echo $ES_HEAP_SIZE
export ES_JAVA_OPTS="-Xms1000m -Xmx2000m" /home/ec2-user/elasticsearch-7.6.0/bin/elasticsearch

$ cd /home/ec2-user/elasticsearch-7.6.0/config
$ vi jvm.options # Make -Xmx1g to -Xmx1g
$ more /home/ec2-user/elasticsearch-7.6.0/config/jvm.options | grep Xm
