使用 docker 安装的 Redis ，版本 7.4.1 ，挂载 config 和 data 文件夹到宿主机，运行一段时间（一个月）后突然发现挂掉了，查看日志有如下信息，看上去像是 aof 文件损坏，如何避免这个问题呢？
1:C 31 Mar 2025 10:15:53.909 # 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.
