问题解答

回答1：

根据官方文档，目前调整了系统参数：上面安装了redisMEM 32GB，

vi /etc/sysctl.conf

vm.overcommit_memory = 1net.ipv4.tcp_syncookies = 1net.ipv4.tcp_tw_reuse = 1net.ipv4.tcp_tw_recycle = 1

vi /etc/profile

ulimit -f unlimitedulimit -t unlimitedulimit -v unlimitedulimit -n 64000ulimit -m unlimitedulimit -u 64000

source /etc/profile

ulimit -a

重启了数据库，插入暂时恢复正常
