asp.net-mvc – Application pool crashes and does not return application

Question:

I have an MVC4 system on .NET 4.0 that is running on IIS 7.

It generates the following error in the Event Viewer:

Custom event details:

I already put the Response.BufferOutput = true ; however it still generates the log.

The worst thing is that after a while the pool crashes and the application stops returning.

Does anyone have any idea what I can do to resolve this issue?

Answer:

Using Response.Redirect is bad business in ASP.NET MVC. The chance of you causing request header collisions is quite high.

Avoid using:

Response.Redirect("/ControllerQualquer", true);

Switch to:

return Redirect("/ControllerQualquer");
