hello,
my controller wlc 5508 reboot unexpectedly,
log console output say: "ENVMON-0-KEEPALIVE: wlcng_powerSupply.c:304 System is rebooting in 5 seconds: lost heartbeat from environmental controller"
i have read "Cisco Bug: CSCtr39523 - AW: 5508 Controller sporadically reboots due to lost heartbeat to EnvCnt".
i have installed firmware 8.0.121.0 , Does anyone else have this problem ?
Thanks

You've got the same problem with 8.0.121.0 ?

I've seen a lot of funny things happening with 8.0.121.0.

In fact I have two wlc (wlca and wlcb) with the same firmware (8.0.121.0).
Wlcb works perfectly while wlca every 30/40 days reboots...

I would upgrade to a different code like Leo mentioned but would probably go to 8.2.151.0. You could also open a TAC case so that they can look at any crash files on the controller. You never know, they might just RMA the controller if they find something.
