Timers: setInterval stops executing the callback

[Emilio]

Hi, I'm having some trouble figuring out whats going on with a timer that I setup with this code:

var cronTasksTimer = setInterval(__.bind(gameServer.runCronTasks, gameServer), 1000 * 10);

If I inspect the cronTasksTimer when the cron is working I see something like:

{ _idleTimeout: 10000,

  _idlePrev: 

   { _idleNext: [Circular],

     _idlePrev: 

      { _idleTimeout: 10000,

        _idlePrev: [Circular],

        _idleNext: [Circular],

        _idleStart: 1402343890428,

        _onTimeout: [Function],

        _repeat: false },

     msecs: 10000,

     ontimeout: [Function: listOnTimeout] },

  _idleNext: 

   { _idleTimeout: 10000,

     _idlePrev: [Circular],

     _idleNext: 

      { _idleNext: [Circular],

        _idlePrev: [Circular],

        msecs: 10000,

        ontimeout: [Function: listOnTimeout] },

     _idleStart: 1402343890428,

     _onTimeout: [Function],

     _repeat: false },

  _idleStart: 1402343898130,

  _onTimeout: [Function: wrapper],

  _repeat: true }

But sometimes the cron function stops working (the callback doesn't run anymore), when this happens I inspect  cronTasksTimer and I see this:

{ _idleTimeout: 10000,

  _idlePrev: null,

  _idleNext: null,

  _idleStart: 1402331871559,

  _onTimeout: [Function: wrapper],

  _repeat: true }

In this state I can execute the cron with:

cronTasksTimer._onTimeout(); // the function works wells.

Any help or clarification on why this could happen would be really appreciated.

My process is running node v0.10.24 on Ubuntu with kernel 3.14.4-x86_64.

Thanks!
