Error in process._tickCallback

[d.host...@geatec.ch]

Hello everyone,

After upgrading from node v0.12.7 to v4.2.3 our application crashes every few hours with the following uncaught exception:

TypeError: Cannot read property 'callback' of undefined

    at process._tickCallback (node.js:341:26)

Could this be a bug in node.js? Our application is quite big and I have no idea how to solve this problem.

The code in src/node.js doesn't look like nextTickQueue() is expected to return undefined:

    // Run callbacks that have no domain.

    // Using domains will cause this to be overridden.

    function _tickCallback() {

      var callback, args, tock;

      do {

        while (tickInfo[kIndex] < tickInfo[kLength]) {

          tock = nextTickQueue[tickInfo[kIndex]++];

          callback = tock.callback;       // <------- line 341. tock is undefined

          args = tock.args;

Any ideas?
