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).

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? Worth it?
Thanks!
