    Exclamation Possible memory leak with GridPanel and Store

    Ext version tested:
    • Ext 3.0.3
    • Ext 3.3.2
    • Ext 3.4.0
    Adapter used:
    • ext
    css used:
    • only default ext-all.css
    Browser versions tested against:
    • IE8
    • IE9
    • FF4.0.1
    • FF6.0.1
    • Chrome 10
    • Chrome 12
    Operating System:
    • Win 7 x64
    • WinXP Pro
    • There is a definite memory increase when using GridPanel with a store. Every time the store is reloaded and grid is rendered, the browser consumes more memory and it does not seem to free it. Best example is IE, which can consume over 1GB and crash within 30 minutes using the attached code.
    Test Case:
    Working code is attached. Unzip it into ext/examples

    Steps to reproduce the problem:
    • Open Click on Autorefresh button
    • Observe memory consumption using e.g. sieve or Sysinternals Process Explorer
    The result that was expected:
    • Stable memory footprint
    The result that occurs instead:
    • Browser starts consuming memory until it crashes
    Debugging already done:
    • none
    Possible fix:
    • not provided
