Two 5508 Controllers Randomly reboot

Hi,

I've got two AIR-CT5508-K9 ( running 8.0.110.0 ) controllers acting as mobility anchors in the DMZ, they are randomly rebooting, I've done a bug search and can't see anything, a Google has found :-

Hi Dexter,

Late last evening, Cisco's senior engineers said we could expect fix code by 
this Monday, and provided this input:

To give you a little background on this bug - this issue is mainly due race 
condition with rogue task and double call/release of a function causing crash.  
Unfortunately all this while until early this month we have not received the 
right dumps from other customers running into this bug hence we could not RCA. 
We have finally received full dump from a customer first week of March to root 
cause and fix this issue by March 5th.

Again- Monday *should* bring relief, and I'm glad Cisco took yesterday's input 
to heart.

-Lee

Anyone know of a definitive version of 8 code that fixes this ?

Regards,

Andy.

Hello 1. this is not a WLCCA

Hello

1. this is not a WLCCA question, so I will move this discussion to the correct forum

2. if you are using 8.0.110.0, and you have webauth observing silent reloads, it is recommended to migrate to 8.0.120.0, that provides significant fixes for mobility, sleeping client and specially webauth scenarios

regards
