      overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add \u2018vm.overcommit_memory = 1\u2019 to\/etc\/sysctl.conf and then reboot or run the command \u2018sysctl vm.overcommit_memory=1\u2019 for this to take effect.<\/strong><\/p>\n<\/li>\n<\/ul>\n

        you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix thisissue run the command \u2018echo never > \/sys\/kernel\/mm\/transparent_hugepage\/enabled\u2019 as root, and add it to your \/etc\/rc.local in order to retain thesetting after a reboot. Redis must be restarted after THP is disabled.<\/strong><\/p>\n<\/li>\n<\/ul>\n
