I'm having an issue in determining what might be causing an ASP, .Net4 web app developed in c# to stop working and display the stack trace page I've attached. I've reviewed the items in the stack trace and they seem to be a red herring. I reviewed the Event Viewer on the server and found that leading up to the eventual disruption of the web app many Informational entries with "Forms authentication failed for the request. Reason: The ticket supplied has expired
" occured. The rest of the event viewer info is in the other attachment.
This just started happening the other night, and I even setup an alternate link from another web server, and the same thing occured. The one change has been in the usage of the system in that it has jumped from 5 simultaneous users to 25-30. After a couple hours without any intervention on my part it will begin working again. I've done a reboot of the server, but that did not help.
There are other web apps on the web server (non asp), and they are not impacted by this. In fact, the web server itself isn't fazed by the ASP app going down.
Any thoughts? I'm not familiar with "Forms authentication failed for the request. Reason: The ticket supplied has expired
", and what it might suggest.
