Dexter, Shame to hear you had those issues. We have been running 8.0.100 without issue since basically it became available. No random reboots or anything along those lines. My opinion the matter is update to it. It has its Caveats but nothing nearly as bad as 7.6 was. Since we have been using it seems like one of the more stable releases Cisco has put out since 7.4.120.

I’m running the 8.0.100.0 code in production. I’d say for now it’s a wait. I like a lot of things about it, but I’ve had two controllers completely die on it to where both were out of production at the same time! Full RMA and everything. I have a plan B, C and D so I was prepared to deal with it, but until we figure out what’s causing our issue, (spontaneous reboots), it’s hard to recommend it for production. More often it seems to happen when there is load but a few times not. It also does not seem to generate a crash log when it occurs so it’s been evasive to troubleshoot. If you can spare to lose a controller or two of and still operate seamlessly, you’ll may wan to consider it. You’ll want to test for sure. There is no question everything is very fast in terms of recovery from restart. It is far faster than what it used to be for us on 7.3. I was willing to deal with the reboots since users barely if ever noticed, but the controllers dyeing was another matter entirely. Two of them rebooted fine one time and another time they rebooted and never recovered. When this occurs, we cannot get any console output. Replacement was the only route. If you’re wondering, not all of these problems show up in test because there are significant load differences. May not be typical, and they’re the only issues I’ve noticed, but they are not trivial.

We’re running 7.6.130.0 in HA in non-VSS 6503 Sup-720/3C chassis, and have come across a bug. It’s documented, and we’re working with Cisco TAC on it. The clients do not see anything (fortunately) but since we’re monitoring the controllers themselves, we see the failover. The last update I had was that it appears to be a memory allocation issue when an activity is taking more than 200 MB of memory, the controller buffer (and I quote) – “is going into a weird state”. The plan is to have an image this week for internal testing (to Cisco). https://tools.cisco.com/bugsearch/bug/CSCur79302 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Hector J Rios Sent: Monday, December 08, 2014 4:08 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Subject: Re: [WIRELESS-LAN] Cisco WLC 8.0.100.0 GO or No Go? We just upgraded to 7.6.130 and has been stable. We are planning to wait a little longer before we consider moving to 8.0. Not sure we will venture to deploy it for the Spring semester.

We are sitting at 7.4.110.0 here, but considering 8.0.100.0 in hopes that we might give maybe a bit better service to mobile users out there. Are you guys moving to 8 for production? Good move?
