Elasticsearch Bootstrap check failed

Elastic Stack Elasticsearch

Im getting below error during elasticsearch start

node validation exception
[1] bootstrap checks failed
[1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]

Im having /etc/sysctl.conf with content as below

vm.max_map_count=262144

If I run sysctl -p, Im getting
vm.max_map_count = 262144

I assume that elasticsearch should start without any error if sysctl.conf is present

But it didnt work that way. Do I need system reboot?

Can you please help?

To set this value permanently, update the vm.max_map_count setting in /etc/sysctl.conf . To verify after rebooting, run sysctl vm.max_map_count .
