Is there a reason you are on that code? I’d start with running the recommended 8.2MR7 interim.

Ours was not great, and what we thought had been resolved, came back to bite us, again. If you want more info, search for subject “Re: [WIRELESS-LAN] Move In/Opening Week- Any Problems?” My question to all of you is the following: If you have Cisco 8540s and over 3000 APs, have you ever moved APs from one controller to another with no issues? i.e. You move 3000 APs from one controller to another at once. Please respond and let me know your basic setup. Here is our problem. Last year we moved all of our APs to an HA pair of 8540. We experienced no issues until the beginning of the fall, when all students came back. Last week, we moved all the APs from one HA pair to another, and right away we started experiencing issues. What is the issue? When the issue starts happening, it appears that a good portion of our APs cannot associate to our controllers. It seems like the controllers run out of resources to be able to establish CAPWAP tunnels (memory leak?). Our configuration: Two HA pairs of 8540s, AP/Client SSO AVC turned on, only on eduroam IPv4/IPv6 dual stack support Our oldest AP model is 1140 Software 8.2.161 (yes, we know it is deferred) 3900 APs ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
