Has anyone problems with accesspoints reboots at high client count (50+ associations per radio)
We have a 5508 WLC with 7.3 Code and 3600 AP´s.
Our problem is that sometimes accesspoints reboots. And this only if a lot of clients are connected.
Many thanks in advance for your help
Yes it is possible that the access points will reboot. There could be a couple different reasons why, most noticeable would be interference caused by so many clients (clients themselves can cause co-channel interference). Is the AP actually rebooting or is the radios resetting due to some reason?

I don´t know the reason why the ap reboot. This is the problem. We monitor the Ap with nagios and we see that the ap is offine for a few minutes. So I believe the ap reboot.
We found no logs on the wlc for the reason.
The problem area is a congress center a so sometimes we have really a lot of users. (like a Cisco Networkers)
We have all the typical problems at high density WLAN. (a lot of Rouge Ap´s, high channel utilization, interference …)
But could that the reason why a accesspoint reboot?
Take a look at the ap uptime and the ap join, that will tell you if the ap has rebooted and or if it lost connection with the WLC.

Ok, look for a crash dump in the controller. Management > Tech Support > AP Crash Log.
If there is NONE, then try the following commands:
1. debug ap enable
2. debug ap command "sh version"; and
3. debug ap disable
Post the output.
As what Scott has mentioned, there are alot of reason why a WAP reboots without any intervention and faulty cabling could also be the culprit.
