Random Appdomain restarts

[J_A5]

Hi,
I recently upgraded my web app from 1.1 to 2.0 and SQL Server 2005. After
the upgrade, I am seeing random appdomain restarts. It was not even logging
any information untill I turned on logging all events in the healthmonitor
section. The appdomain restart is logged as an info event. The event log is
as below. The only other place where I could find a discussion on this issue
was at http://forums.asp.net/thread/1222731.aspx. Has anyone else found
similar problem or has a solution for this issue?

Event Type: Error
Event Source: .NET Runtime
Event Category: None
Event ID: 0

message DLL files to display messages from a remote computer. You may be
able to use the /AUXSOURCE= flag to retrieve this description; see Help and
Support for details. The following information is part of the event:

Thanks in advance,

There are any number of reasons why the application might restart. Some of
them are quite normal. For example, an application will shut down after a
period of inactivity. So, just from the information you've provided, there's
no way to know *why* the app is shutting down. All it says is that the
application has shut down.

Yes I understand that there are several reasons such as period of
inactivity, preset time in IIS6, too much memory utilization, config change,
bin folder change etc. In my situation none of those common reasons are
valid. Also, if you look at the log information, the app recylce reason is
specified as

The message clearly says that the shutdown was due to overwhelming change
notification. What I did was just compile and log in to my app. After few
pages, it timed out for no apparent reason. This happens randomly.

Thanks,

Yeah, sorry, I overlooked that part of the exception message.

Are you using any custom caching in your application?

Here is an article about caching that may contain a clue as to your problem:
