How to Fix EventQueue.ProcessMessage: Message Processing Failed

Another bug with DotNetNuke 4.8 release comes up when you install Media module via browsing Host > Module Definitions page.

After succesful installation wait for a while and you will end up seeing following error in Admin > Event Viewer.

To fix this problem i made some research and found a discussion at following topic. According to John's post, this error happens because of Media module is trying to upgrade itself from a previous version of Image module. However DNN 4.8 Installation package does not contain old Image module.

To gain more info, i opened up EventQueue table in my database by connecting to MSSQL Server 2005 via Microsoft SQL Server Management Studio and noticed that one of the Application_Start event has IsComplete flag set to false. In my environment it has 14 as EventMessageID. I simply set IsComplete flag for this entry to true. Then saved my changes.

It has been 2 hours since this last change and it seems like error gone :)

I also reported this issue to Gemini for permanent solution.
