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。
