It happens at random times at random pages on the site with or without any ajax controls (other than the toolkitscriptmanager on the master page).


Comments: At lease some traction. I have not had a chance to debug nor really thought of it because it doesn't happen that often for the number of hits we have on our sites...but it is a serious issue. Do you have an idea of a quick fix/Band-Aid until they come out with a new version? I looked at your profile it seems you are not part of the project... Thanks.
