Can you recreate the issue consistently and if so how?

not really. each client sees an error at a different time. i thought it was cache related, but i cleared it and set it to clear at like 1 am..still, the clients see this as a pop up and the above gets logged.

im wondering if i recompiled improperly.. the only thing ive compiled for was the shoutbox. since you compiled the only DLL needed. i replaced all my dll's with the ones from the release, except for the yaf.classes.data.dll one you compiled. ill see if the error shows again.

i also searched for one of the errors in the event log statement on the server.. found this

http://support.microsoft.com/kb/555353 

it suggests this for the solution..?? is making a machine key the answer? i know galleryserverpro.com's products uses that.

1. Adjust the settings on the application pools so that recycling is less likely to occur at peak periods.
2. Use a specific key in the machine.config to prevent automatic key generation on each process start
3. Only post to the same ASPX page
4. Turn off firewall and antivirus software
