ASP Chart Issue on IIS7

Hello All,

I have hosted a ASP.NET web application(.Net 4.0) in 2 different servers(Load balance configured) and both settings are common but some days after a server is not loading the asp chart still another server is working fine.

if restart app pool and then its working after couple of day then again same issue.

below shared my config settings for your reference,

HttpHander,

<add path="ChartImg.axd" verb="GET,HEAD,POST" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" validate="false"/>

Handler

<add name="ChartImageHandler" preCondition="integratedMode" verb="GET,HEAD,POST" path="ChartImg.axd" type="System.Web.UI.DataVisualization.Charting.ChartHttpHandler, System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

Assembly

<add assembly="System.Web.DataVisualization, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>

AppSettings

Any guess what is wrong here?
