At present, a scenario has been found that there are too many ipmi messages in a short period of time, and a large number of users and messages are blocked in the ipmi modules, resulting in a large amount of system memory being occupied by ipmi, and ipmi communication always fails.
Frequent calls ipmi and failure of hardware communication will cause this exception. And ipmi has no way to detect and perceive this problem, therefore it is impossible to located and perceived online. This patch provides a method to view the current number of users and messages in ipmi, and introduce a simple interface to clear the message queue.
