感谢您的输入。从日志的最后几行，您可以看到内核报告的vm总使用量为71339176kB（~71GiB），而vm总使用量应包括物理内存和交换空间。此外，日志显示驻留内存约为69GiB 在这种情况下，我对碎片的理解正确吗 如果在问题发生或报告期间捕获系统诊断，请检查
/proc/buddyinfosysctl-a
vm.overmit_内存=2
vm.overmit_比率=80
/etc/sysctl.conf1-无论内存是否可用，总是过度分配（很可能在服务器上设置为0或1）。 2-这告诉内核允许应用程序提交所有交换+%的ram，为此还应设置以下值（例如：设置为80%）
2-使用此选项将不允许过度使用内存（超出可用RAM+80%的交换空间）对碎片的理解是不正确的。发出oom是因为内存水印被破坏。看看这个：
