【问题描述】错误码:COM10999
错误信息:发生一个未知的错误，错误原因:ocp agent processes not running，错误信息:(1)，请联系管理员。
OS:Kylin Linux Advanced Server V10 (Tercel) 安装oceanbase-all-in-one 部署OCP 完成后，登录总会提示：Install ocp agent 执行失败。
解决办法：
echo "vm.max_map_count=655360" >> /etc/sysctl.conf
echo "fs.aio-max-nr=1048576" >> /etc/sysctl.conf
echo "kernel.pid_max=4194304" >> /etc/sysctl.conf
[root@obocp ~]# pgrep -a “”
pgrep: cannot allocate 4611686018427387903 bytes
[root@obocp ~]# # 只查OceanBase相关进程
[root@obocp ~]# pgrep -a observer
pgrep: cannot allocate 4611686018427387903 bytes
这里还是没解决不是参数问题
[root@obocp ~]# yum install -y procps

报错数字 4611686018427387903 是无符号整数溢出假象，不是物理内存不足：
pgrep 全量查询报超大内存分配溢出是 麒麟 V10 自带 pgrep 工具自身 bug，和系统内存、内核参数无关，不影响 OBD、OB、OCP 正常运行；
麒麟 V10 自带 procps 版本老旧存在溢出 bug，升级工具包：
yum install -y procps
