Setup and configuration

Hi,

Has anyone else seen this warning come through on the Redis Logs??? (I couldn’t see anything on here)

and implemented the recommendation?

chirpstack-redis                   | 1:C 21 Jan 2024 23:37:55.851 # WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can also cause failures without low memory condition, see https://github.com/jemalloc/jemalloc/issues/1328. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
