SharePoint Webpart deserialize error

Question

I am getting a random web part error, it works one refresh and then not the next:

Web Part Error: One of the properties of the web part has an incorrect format. Windows SharePoint services cannot deserialize the Web Part. Check the format of the properties and try again.

The web parts have been on the site for a long time, and I have checked Micorsoft Support, http://support.microsoft.com/kb/826786 . And it is not a permision error becuase it has been this way for a long time. The only thing changed in regards to webparts was going into Site settings > Web Parts > New and selected some webparts that were not in the list and I think I also Checked the ones that are having this random error and clicked "Populae Gallery". Any body have a clue?

This could also be because of insufficient disk space on the server where SharePoint is hosted. http://www.sharepointblogs.com/vipul/archive/2006/09/25/webpart-error-due-to-space-crunch.aspx Check the available disk space.

Hope this helps.

Have you tried rebooting your server. I have just recovered from this exact problem. One of my frontend servers ran out of disk space yesterday and I recovered 10Gb of it, however this didn't rectify the error I was receiving when trying to view or add page viewer webparts until I rebooted it. All is perfectly fine now.

We also had this issue as well as search was failing, and there appeared to be no disk space issues. I performed an IISRESET /noforce on all three servers in our farm. The iis reset of the last one failed so I did a more forceful reset and everything started working again.
