Question

i have created one web application in asp.net[.net 4 framework and visual studio 2010].Now i am running with IIS 5.1 version.When i running my application, i am getting the following error

Server Application Unavailable

I am also checked with EventViewer… It says

Event ID:   1001

Description:
aspnet_wp.exe  (PID: 1724) was recycled because memory consumption exceeded the 1221 MB (60 percent of available RAM).

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

I dont know how to resolve this issue? Is there any way to increase the memory consumption limit of RAM for my IIS.

Please guide me to get out of this issue…

Answer 1

Bottom line – you should debug the code to seee why it takes this much memory.

But to answer your actual question, yes, there is a way to increase this limit.

In the machine.config file there is a section named ‘processModel’ and by default it looks like this:

<processModel autoConfig="true"/>

If you change it to add a ‘memoryLimit’ value this will modify the percentage value used to determine when to recycle the process. For example:

<processModel autoConfig="true" memoryLimit="90"/>

This would allow the process to consume 90% of available RAM before the process was recycled. The default is ’60’. You can of course also set a lower value.
