I have a problem which is steadily becoming more and more frequent.
I have a visitor wireless network using web-auth which works just fine most of the time. Visitors turn on their wifi, associate to the visitor network and open a browser which redirects to the authentication page which is hosted on the 4404 WLC. This has worked fine for a couple of years. About 6 months ago I had an issue where visitors were unable to reach the authentication page. They were able to associate to the visitor service, pick up an IP using a seperate DHCP service, resolve the IP of the webpage and I was able to see them on the controller. It appears that the controller just stops serving the authentication webpage. I looks like the built in webserver has frozen/crashed. The only way I have been able to rectify the issue is by restarting the controller, but this kicks off all my other users that are using our other wireless service (WPA + WPA2 Auth(802.1X)). This is obviously somthing that cant go on.
Has anyone else had this issue. Is it possible to restart the emweb http daemon without a system restart? This problem is reocuring more and more now, its now a weekly problem.
I have several WLC 4402's and a 4404, this problem is only effecting the 4404 and 1 of the 4402's ( at diferent times).
WCS Software Version 188.8.131.52
4404 Software Version 184.108.40.206
4402 Software Version 220.127.116.11
Fixed in 5.2.193 and later.
And you don't need that heavy load to make it die by the way. That bug has been faced by thousands of people on your verison
Hope this helps.
