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?
