该系统主机数据库监听服务器，启停不超过5分钟就会自动重启。业务短暂的受到影响。重启过操作系统网卡APA服务后，3个月又开始频繁重启。

xx.xx.89.3_aop数据库，监听总是重启。经过在Oracle Support官网查询，及其与一个bug相匹配。

meatlink Bug 16039587 。

HP UNIX下需要操作系统打个补丁：

Cause

The issue was investigated in Bug 16039587, the cause is HP-UX bug, basically the contention of address memory range lock on kernel memory causes poll(2) timeout and affects orarootagent process.

Solution

Apply OS kernel patch PHKL_42850.

找到相关补丁，进行了工单审批，到实施完成。AOP数据库监听闪断重大隐患已经解决。
