    [OPEN] [#10] Memory leaks‎


    We are moving our MVC applitacion, in a very long and hard work, to the new Ext.NET 2.1 version. In this way, we have detected a huge memory leak problem using this new version.

    When we open Tabs or Windows (in our case, windows are open dynamically via script), the explorer process has a great memory increase. But when we close a tab or a windows, there is only an small decrease. So, when we are working with the application a little bit, we can get 1GB of process memory in a moment.

    We have tested Ext.NET 2.0 examples page, opening and closing tabs, and we have detected this problem too.

    We have tested too previous Ext.NET 1.X versions (examples page and our application also), and it looks like memory tends to remain more stable. So it sounds liake a problem with the new version.

    In our case, it looks like Firefox deals better with these memory leaks than IE and Chrome browsers.

    This is a critical issue for us, so we are looking to know for you about how to solve this problem.

    Do you have the same problem with Examples Explorer?

    We cannot say anything concrete without a sample to reproduce the issue

    Yes, I can confirm it.
    IFrame mode is problem. The problem is reproducible on pure ExtJS samples
    For example, if open samples from http://docs.sencha.com/ext-js/4-1/#!/example then the memory grows
    I will report to Sencha about it

    I am affraid that we cannot give solution at this time because the problem in ExtJS toolkit
    We are waiting confirmation from Sencha

    We hope Sencha will consider this as a very important bug, due to its critical impact.

    As we can't deal with Sencha directly, we hope also you will take care of Ext.NET customers interest as usual.

    We hope too.

    By the way, here is the Sencha thread with the report.
