IIS4 crashes when displaying multiple charts!

User (Legacy) · September 18, 2000

Hi!
My webserver (specifikation below) keeps craching whenever I try show more

than one chart (JPEG in CfxTemp) at a time.

I have NO problem at all with one chart, but as soon I used a loop to

generate 5 charts IIS craches.

The WWW-services does NOT stop, IIS Manager does not start and I can not

used Controlpanel/Services to stop It eather.

So the only solution is restart and in most cases cold restart by pressing

the ON/OFF button.

I have isolated the problem area (code below), and tried different methods

to avoide taking down the webserver. I've made the directory a Application

that runs in own memory space, without result. I still have to restart!

   ' Title Settings

   ChartFX1.Title(2) = arBudget(intKPI, 1)

   ChartFX1.RGBFont(2) = &HFFFFFF

   ChartFX1.Fonts(2) = 256 'Bold

 ChartFX1.OpenDataEx COD_VALUES, 4, 6

   For intSeries = 0 To 3

    For intPoint = 0 To 5

     ChartFX1.Series(intSeries).YValue(intPoint) = arDiagram(intKPI,

intSeries, intPoint)

    Next

   Next

 ChartFX1.CloseData COD_VALUES

   strHTML = ChartFX1.GetHtmlTag(300,200,"JPEG","ChartFX1")
