当Linux系统中的vm.overcommit_memory参数设置为0时,内核会采用启发式(Heuristic)算法来决定是否允许内存过量使用(overcommit)。这种设置下,如果系统判断内存不足,可能会拒绝内存分配请求,从而可能导致Redis在低内存条件下无法成功进行后台保存操作。 解决方案 修改vm.overcommit_memory参数: 将vm.overcommit_memory设置为1,...
Background save may fail under low memory condition. 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. 内核参数overcommit_memory 它是内存分配策略。可选值:0、1、2。 0:表示内...
需要在服务器上执行sysctl vm.overcommit_memory=1或者执行一下语句: echo"vm.overcommit_memory = 1">> /etc/sysctl.conf \&& sysctl -p
and then reboot or run the command'sysctl vm.overcommit_memory=1'forthisto take effect. 警告超委托内存设置为0!后台保存可能在低内存条件下失败。要解决此问题,请将“vm.overcommit_.=1”添加到/etc/sysctl.conf,然后重新启动或运行命令“sysctl vm.overcommit_.=1”,以使其生效。 2. 解决办法: 其实报...

echo 1 > /proc/sys/vm/overcommit_memory 这个命令进行配置 但是为什么这么设置呢。我来解释一下参数: 0, 表示内核将检查是否有足够的可用内存供应用进程使用;如果有足够的可用内存,内存申请允许;否则,内存申请失败,并把错误返回给应用进程。1, 表示内核允许分配所有的物理内存,而不管当前的内存状态如何。2, 表示...
