此问题是 Redis 默认会使用 jemalloc , 因为 jemalloc 被证明比 libc 有更少的碎片问题，但是我的系统中没有 jemalloc ，所以会出错

下面是来自源码中 README 的申明

Allocator

Selecting a non-default memory allocator when building Redis is done by setting

the MALLOC environment variable. Redis is compiled and linked against libc

malloc by default, with the exception of jemalloc being the default on Linux

systems. This default was picked because jemalloc has proven to have fewer

fragmentation problems than libc malloc.

To force compiling against libc malloc, use:

% make MALLOC=libc

To compile against jemalloc on Mac OS X systems, use:

% make MALLOC=jemalloc
