W3WP Crash

description

Hi,

We had created a website using WCSF framework and .NET 2.0.

Currently this application is live and used by more than 1000 users. We have deployed this in a cloud in IIS 7 under Windows 2008 Server R2. We also use Sql Server 2008 R2 database for the backend. The deployment architecture is as described below.

There are two web servers connected under a load balancer (Hardware based) using sticky sessions. These two servers communicates with two database servers with more than 600 databases scattered evenly between them. All requests will first go to a admin database which redirects to the appropriate db server.

Now to the issue....

We are getting around 4 to 5 w3wp crashes per day in both the servers. During this time all the users connected to the application will be logged out.

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2
Faulting module name: KERNELBASE.dll, version: 6.1.7601.18229, time stamp: 0x51fb1677
Exception code: 0xe053534f
Fault offset: 0x000000000000940d
Faulting process id: 0x%9
Faulting application start time: 0x%10
Faulting application path: %11
Faulting module path: %12
Report Id: %13

Recently we opened a case with MS and their comments is in the attached file.

We are not sure where to look for the issue at the moment and if anybody could help us to solve the issue it would be very much appreciated.

Thanks,
Anup
