    Hi All,

    Mysql service is going down continously in my system due to lack of memory
    space.

    I checked the messages log and found the following error message.

    All mbuf clusters exhausted, please see tuning(7).

    I have no idea about mbuf cluster. Can anyone please help me to fix the issue.

    I hope the information below will help you.

    Following is the output of top.
