  • Mysqld memory load

    I'm using version: 5.5.28-29.1 Percona Server (GPL), Release 29.1
    3 days ago mysql starts to eat more memory, than usually.
    And I can`t find why. Load is the same for a long period of time.
    Restart doesn`t help.
    I`ve attached munin graph. Can anyone help to find problem?

    You mean it is using less memory. Maybe you restarted it, and old pages do not fill the buffer pool as they have not been read yet.

      I mean that Percona was using less memory than now.

        The graph shows that 3 days ago the memory usage dropped from 40 GB to 15 GB, so I don't understand you.

          Memory dropped because of upgrade && restart of php-fpm daemon. Unknown is - why percona started to use around 5G of ram? for a long period of time it was using around 1G.
