  • Need Concord Linux test

    Who else is running Linux and the Concord plugin? I need to check the file descriptor usage for the plugin. One user has a lot of FD being opened, and I can't determine if it's a Mono, garbage collector, plugin or panel issue.

    What I need is:

    sudo lsof |grep CONCORDDB|wc

    If you're running a generic PI you might need to apt-get lsof

    Thanks,
    Z

    Never mind

    Turns out Mono's not as forgiving about open SQLite.SQLcommand and dataReader calls as Windows is. They all have to be "disposed" of before you close/dispose a DB Connection, otherwise it fails and you end up with a gazillion file descriptors
    Looks like the new Mono garbage collector (SGen) kept up with it well enough that it took a busy system (many sensitive motion sensors) before it ran out of file descriptors.

    3.1.13.3 out as soon as it's run for a couple of days..
