Hi Jeff- No resource issues, and the same Auth servers used elsewhere are fine- all traffic stops, not just post-auth DHCP.

Lee, Does anything look out of the ordinary on the problem controller i.e. memory use rising, CPU spikes, etc.? Any authentication involved your SSIDs? If so, is the authentication source slow to respond? Jeff >>> Lee H Badman <[email protected]> 08/30/09 3:38 PM >>> Wondering if we're alone in this experience. We had a great opening weekend in that thousands of users got on our secure wireless network with little fanfare. Then tonight, multiple controllers seemed to have simple "frozen" for lack of a better description- all indicators were fine except dhcp renewals and new requests were not getting back to the clients, and established users' traffic stalled. The fix seemed to be moving APs to another controller, booting the one with the stall condition, and moving the APs back. Simply rebooting APs didn't seem to touch it. Anyone experience similar? We've never seen anything like this on past versions. I'm not pointing fingers at the code at this point, but would be curious if anyone else has seen the same sort of problem. Lee H.
