Forgive my repeated posts. The forums are rejecting my posts from the word S c a n A l e r t.

Welll, well. Ain't t that funny. I did not know you could not use the word "A l e r t" in your post. It cuts off everything after the word.

a lert works but "

Add me to the list of users experiencing the problem. I am running 4.7 and on an Intranet - so an outside site hitting the site is not possible. I have 1 web/db server with 4 child portals running (parent portal not used). It has been running for two years, mostly under a 3.x version but upgraded it a few months ago to 4.X. It seems to happen to fresh as well as old installs of DNN.

Here is what I have done in the past week to hopeful get rid of the problem:

First Occurance
1) Turned off IIS logging - Extended Logging was ON
2) Moved 3GBs of IIS log files into a subfolder

6 Days later it happened again
1) Defragged the HD's
2) Added and Indexes and Statistics to my custom module tables
3) Altered 1 record from -1 to 0 in the DesktopModules to Module MarketPlace
4) Refreshed all my existing stats and indexs in the database.

3 Days later it happened again
1) Changed Host Settings to NO CACHE

UPDATE: It hasnt happend for 2 weeks now!!

I will post back here if it happens again and or I figure out the solution. Time will tell.

Its because of a new filter added to try and make sure that the javascript "A l e r t" box is removed from the text. I expect Cathal was a bit heavy handed with his Regex as it is matching all uses of the word "A lert" not just the js ones.

Question for all those experiencing this issue.

Are your sites busy sites?

There is a known issue with datareaders getting mixed up by ADO.NET - which may cause issues if the objects are not filled and are returned as nothing.

Ok - follow up to my ealier comment.

I think this issue (which relates to the TabPath Dictionary) is similar to this other issue.

This is not as easy to confirm for sure - as the exceptions are all slightly different - other than they are caused by an attempt to insert something into a null dictionary OR use a null value as the index.

Regardless I think they are both due to caching issues with the cache expiring between retrieving the item and attempting to use it.
