application that I have in testing right now and I'm seeing this a
couple dozen times a day. I'm not sure how to begin troubleshooting
this:

Thanks:

"Application Pool Recycling
IIS 6 will periodically recycle the application pool to
maintain the health of the application pool. At the instance when the
application pool is being recycled, browser requests may sometimes
result in an invalid viewstate error. The fix in this case is to
adjust the settings on the application pools so that recycling is less
likely to occur at peak periods. This issue represents a bug since the
application pool is supposed to gracefully handle this condition."

I set the pool to only recycle during non-working hours and I haven't
had an instance of this since.

Hello,

I have the same problem and setting the pool to only recycle during
non-working hours doesn't solve it either..... Do you have any other
suggestions that I can try? My application is ASP.net 2.0.

Thank you in advance,
Chieko
