Hello all,

Over the past few days, I've been bringing a 3.2.2 up to date to version 4.8.2. My setup:

• Windows Server 2003 Standard PS1
• SQL Server 2005 Enterprise
• ASP.NET 2.0

I've upgraded using the following DNN versions:

• 3.2.2 (Initial version)
• 3.7.7
• 4.4.1
• 4.8.2
• Upgrading using Install.zip packages (I've also tried using the Upgrade.zip file, which rendered the same result)

Upgrades ran surprisingly smooth up to 4.4.1 to 4.8.2 where I get the following error:

I've read several posts about this error, mainly curly brakets issue fixed in 4.4.0, none of which seem to apply to my setup.

A few notes:

• The error does not always occure at the same place. Above the error occured at Installing Module File Adsense_01.00.01_Install but it doesn't always occure at that step, but always after Performing General Upgrades which seem to take an awful long time to complete (> 1min.).
• The w3wp.exe is taking up a lot of CPU time.

Any insight about this issue will be greatly appreciated

Thanks Drew, I'll give it a show.

Noticed that having the EnableCachePersistence="True" puts a significant load on the CPU. I managed to successfully complete my installation after setting this value to false.

< appSettings><add key="EnableCachePersistence" value="false" />
