DNN Genii,

I have quite a number of these entries in my Event Load. I am not clear what the message means. Any suggestions would be appreciated.

Thanks in advance

please see http://www.dotnetnuke.com/Resources/Wiki/Page/Viewstate.aspx - it's probably being caused by app pool reloads or users taking too long to post content - that page offers fuller explanations. Note: 6.0.1 added some code to suppress some of these messages where they were not necessary, so an upgrade to that version will likely reduce the noise you see in the event log
