今天在程序中，jedis put数据到redis过程中，“MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk”报错；

再查看Redis日志，看到有这样的错误提示“Can’t save in background: fork: Cannot allocate memory”，这个提示很明显"Fork进程时内存不够用了！"，但内存明明还有一个多G；

经网上查询，Redis在保存数据到硬盘时为了避免主进程假死，需要Fork一份主进程，然后在Fork进程内完成数据保存到硬盘的操作，如果主进程使用了4GB的内存，Fork子进程的时候需要额外的4GB，此时内存就不够了，Fork失败，进而数据保存硬盘也失败了。

解决如下：

执行命令 sysctl vm.overcommit_memory=1

/etc/sysctl.conf 文件添加

vm.overcommit_memory=1
