# Infinite Loading

On some occasions we observed the following error popping up in the browsers developer console. At the same time you can observe in the browsers developer tools network tab that the JENTIS JS file is loaded infinite times.

{% hint style="danger" %}
Uncaught RangeError

Maximum call stack size exceeded
{% endhint %}

**Root cause**: the JENTIS basic tracking code snippet is loaded on a page multiple times.

**Solution**: Make sure to load the JENTIS tracking code snippet once on a page. Adding the same code twice to a page will result in JENTIS loading the according JS file in an infinite loop.
