ArgumentNullException in SiteMapNode when accessing any page in portal

Posted on by yleclerc 1,549

Our AdxStudi Portal goes offline from time to time, without anyone even accessing it. We have no idea why.

When the problem occurs, we need to recycle the application pool on which the portal runs. Then the portal runs fune for a few hours or so.

I've encountered similar posts, but no answer so far.

Here is the log:


System.ArgumentNullException: Value cannot be null.

Parameter name: key

    Turns out we had a couple of web pages without a parent page. That seemed to resolve the issue.
