A process serving application pool 'AppPool' suffered a fatal communication error

We have a serious problem with a .net 2.0 application that makes the IIS
process crash.

The following is logges ind the Event log


Event Type: Warning
Event Source: W3SVC
Event Category: None
Event ID: 1011
Date: 07-01-2006
Time: 22:21:10
User: N/A
Computer: TIGRIS
Description:
A process serving application pool 'AppPool' suffered a fatal communication
error with the World Wide Web Publishing Service. The process id was '6468'.
The data field contains the error number.

For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.
Data:
0000: 6d 00 07 80 m..?



I have searched the Internet and found a lot of suggestions regarding the
Registry database where Network Service should be granted access to several
keys.
I have done that with out any luck and monitored the registry to find other
keys. Both the Process user and Network Service is granted full access.

Sounds like a process is crashing. Could be anything - and most likely not
a regkey issue.

Run IISState against w3wp.exe:

iisstate -p <pid> -sc -d <enter>

And post the resulting log.

Hi Claus,

Welcome to MSDN newsgroup!

As Pat mentioned, the issue seems to be that the IIS process has been
crashed. The IISState tool is good for the current problem. But if you want
to use some tools with GUI, I suggest you use the ¡°Debug Diagnostics¡±
tool from the Microsoft Beta site to debug the current process. You can
follow the steps below to get the tool:

1. Go to http://beta.microsoft.com
2. Login in with your passport id.
3. Login using the guest ID "DebugDiag" (it's case sensitive)
4. Click on the "IIS Debug Diagnostic Tool" link.
5. On the left hand side expand survey and select "IIS Debug Diagnostic
Tool Nomination Form"

Note: if the customer only wants DebugDiag and doesn't want to sign up for
the beta they can do this by selecting "Click here to download IIS Debug
Diagnostic Tool" from the File Downloads section.

When the installation is finished, you can create an IIS hang dump file and
analyze it. After analyzing, please post the report file (.mht format)
here, it will help us to find some details. Thanks for your understanding!
I¡¯m looking forward your reply!

Regards,

Yuan Ren

It is usually better to diagnose the actual issue and not pattern match
against one of gazillion possible distinct solutions.
