@文心快码overcommit_memory is set to 0 文心快码 overcommit_memory 的含义 overcommit_memory 是一个内核参数,用于控制 Linux 系统上的内存分配策略。它决定了内核在面对内存分配请求时,是否允许进程分配超过物理内存加上交换空间(swap space)总和的内存量。简而言之,它控制了系统是否允许“过度提交”内存。
但是看了下/proc/sys/vm/overcommit_memory的默认值是0,redis 最大内存8000000000bytes 我64G内存的服务器,当初出问题的时候free –g看了下内存可用和free都比较多,照理用0也应该没问题。不清楚是不是因为不合理的overcommit会被拒绝。
