Hi! I had a problem - the server disconnects all clients of application at different time intervals.

How can I find the cause of the error and it is better to fix it? )

    I found out that the error occurs after a some number of calls pushData:

    application.interval[streamObj.name] = setInterval(application.pushData, 200, streamObj.name);

    Even if application.pushData has an empty body!

    Also sometimes there is another error in /var/log/messages with the same result:

    May 29 17:18:20 L603 kernel: [168543.420719] fmscore[20496]: segfault at 0 ip (null) sp 00007f0c260cdf88 error 14 in fmscore[400000+ab4000]

    If I set RuntimeSize to some big number, then between the drops is more time but still the error still occurs even if RuntimeSize takes all my memory.

    Are you using the ClearInterval along with SetInterval , Can you also give us the code snippet where this is occuring so that we can reproduce if possible ?

    Thank you !

    application.onAppStart = function()

    {

        trace("Starting Live Service...");

    application.group = new Array();

    application.interval = new Array();

    application.netGroup = new Array();

    }

    application.onPublish = function (clientObj, streamObj)

    {

        trace("The stream " + streamObj.name + " now publishing");

    s = Stream.get("raw:" + streamObj.name);  // record stream to raw format

    s.play(streamObj.name);

    s.record("record");

    var groupSpecifier = new GroupSpecifier("com.gg." + streamObj.name);

    groupSpecifier.postingEnabled = true;

    groupSpecifier.serverChannelEnabled = true;

    groupSpecifier.routingEnabled = true;

    groupSpecifier.objectReplicationEnabled = true;

    groupSpecifier.makeUnique();

    application.group[streamObj.name] = groupSpecifier.toString();

    trace(streamObj.name + " = " + application.group[streamObj.name]);

    var nc = new NetConnection();

    nc.connect("rtmfp://localhost:53333/dvr");

    nc.onStatus = function(info){

    trace(info.code);

        if (info.code == "NetConnection.Connect.Success") {

    var ng = new NetGroup(this, application.group[streamObj.name]);

    application.netGroup[streamObj.name] = ng;

    ng.onStatus = function(info){

    }

            }

        }

    application.interval[streamObj.name] = setInterval(application.pushData, 500, streamObj.name);

    var shObj = SharedObject.get(streamObj.name, false);

    shObj.clear();

    shObj.setProperty("group", application.group[streamObj.name]);

    }

    application.pushData = function (streamName) {

         //empty body for testing

    }

    application.onUnpublish = function (clientObj, streamObj)

    {

    trace("The stream " + streamObj.name + " now unpublishing");

    clearInterval(application.interval[streamObj.name]);

    }

    Then I starting streaming using FMLE 3.2 with bitrate 800-1500. Everything works fine from 30 minutes to a couple of hours:

    'watch free -m' shows a gradual decrease in available RAM

    4096mb total RAM installed, RuntimeSize=1000000. If I set RuntimeSize=1000 then the application falls much faster.
