Hi all, I have a critical problem in my production websites, I've read all the forums related to this issue and nothing has worked.
Enviroment:
2 DFS Servers (DFS1 and DFS2) - Windows Server 2008 R2 64 Bits, lastest patches installed, (Xeon x8 With 8Gb Ram)
- Both are active directory and DNS Servers too
- Shared configuration of web servers resides in this servers in a share and sincronized folder : C:\replicated\Shared config
- Production Web Site Folder in: C:\replicated\wwwroot\www.mysite.com, replicated with dfs
2 Web Servers (WEB1 and WEB2)- Windows Server 2008 R2 64 Bits, lastest patches installed, (Xeon x8 With 8Gb Ram)
- ASP.NET Framework 4.5 Installed
- Shared Configuration (\\mydomain.local\IIS\replicated\Shared config)
- application pool : www.mysite.com, .Net Framework v4.0, Classic
- web site mydomain.com
In the event viewer i saw this:
System logs: A process serving application pool 'mysitie.com' suffered a fatal communication error with the Windows Process Activation Service. The process id was '5236'. The data field contains the error number.

/>
What can be changing my site files automatically to make my application pool to be recycled?
i try with, File Change Notifications, Global.asax configuration, debuggin, no antivirus running on my server or tools that I can scan or modify files, nothing is uploaded to the site in moments of failure, there is no time relationship for this happen.
I forced a permit changing error in the web.config, also try with maxWait time, etc, etc, without success, this causes the app crash my users sessions end unexpectedly.
I appreciate your help, I am fully available to analyze what you suggest to resolve this.
