To                         fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_m                        emory=1' for this to take effect.
4093:M 24 Oct 12:32:48.593 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create                         latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugep                        age/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarte                        d after THP is disabled.
