涉及到redis服务异常，触发了oom，redis服务被系统kill掉。
Jan 29 05:59:37 s81 kernel: ecnet.exe invoked oom-killer: gfp_mask=0x201da, order=0, oom_score_adj=0
Jan 29 05:59:37 s81 kernel: Out of memory: Kill process 751 (redis-server) score 260 or sacrifice child

调整系统参数，增加vm.overcommit_memory=1，试图应对无法分配内存的异常。

1）一定要设置最大内存
2）多留一倍内存
