Im getting below error during elasticsearch start
node validation exception
 bootstrap checks failed
: max virtual memory areas vm.max_map_count  is too low, increase to at least 
Im having /etc/sysctl.conf with content as below
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?
