current memory status.2. indicates that the kernel is allowed to allocate more memory than the total physical memory and swap space.Redis generates a sub-process when dumping data. In theory, the memory occupied by the child process is the same as that of the parent. For example, the parent occupies 8 GB of memory, at this time, 8 GB of memory should also be allocated to the child. If the memory is not enough, it will often cause the redis server to
