Have you recently upgraded the base DNN install or any modules? Are you doing custom development on the site or using a new/updated skin? What version of DNN is this?

The problem appears, from the error, to be related to the container's actions (and client-side oriented) and something likely changed in the environment recently that caused this.

I notice by the file names (Pane.vb etc.) that you're using a very old version of DNN (prior to 6.0) -as Chris says theres a good chance that something environmental (such as the .net version, which affects the MS Ajax version which is also mentioned in the stack trace) has changed and is not working well with that older version. I'd suggest you consider testing an upgrade to a more recent version - if nothing else that will ensure that you're not running a site with known security issues (http://www.dnnsoftware.com/platform/m...)

Hi Chris,

DNN and existing modules are not upgraded, DNN version is 5.1.1 still same version in use. Installed new DNN skin (3rd party skin) 10 months before.

And yes regarding custom development, Login module will undergo frequent changes other modules are not disturbed.

We use this version for past 5 years and recent times usage is around 100 users per day and the exception raised approx 10 to 15 times a day and due to this exception app pool gets fulled and site stops working.

Hi Cathal,

 Yes DNN version is 5.1.1 and 10 months before we changed the .net framework version from 2.0 to 3.5, but if the issue is related to version or environment changes then exception would have raised for all users accessing the portal. On an average we have 100 users accessing the portal but eventlog captures 10 to 15 exceptions per day.
