hi,

Meanwhile, while going through the stack trace and running through the code [the old fashion "find" way], I think i have found where the error is occuring, but am not sure whats the solution. The error that I got is as below.  I followed the stack and reached the DotNetNuke_04.05.05_Source\Library\Components\Tabs\TabInfo.vb file which gets populated with all the variables and values of a tab and there's only one collection among all the properties being filled up and that is at line 278

        <XmlArray("tabpermissions"), XmlArrayItem("permission")> Public Property TabPermissions() As Security.Permissions.TabPermissionCollection

Would this be the cause?  HELP...this is occurring on our PROD server!  Is anyone from the Dotnetnuke core team seeing this!

regards
harish

We are also trying to run down this problem.  If we figure out anything we will pass it on to you.  Will you please let us know if you also discover a solution?

Thanks

L. Nick

We have already tried that, still the error will keeping showing at regular intervals, especially after the application restart.
