[cisco-voip] CUCM 8.6.2...where?

Thu Oct 6 00:44:51 EDT 2011

8.0.2c-ish was pulled for a sev1 issue as well, iirc.

These issues aren't always as easy to catch before release as what you might think.  As the product grows more complex, so does the potential for these types of problems.  Realistically, to prevent these types of issues entirely Cisco would have to slow their feature / product release schedule to a comparable crawl.

I think they do a good job of removing the offending version from CCO and immediately stopping the release of physical media of the version, and they also replace that version with a more stable release pretty quickly.  It is nice, as a partner or end-customer, to sometimes let the bleeding edge releases bake for a few weeks though.

How many other CUCM releases have been pulled for deferral like this?  Sincerely asking because I'm not aware of others.  I was under the impression these things were getting better.  At least I've got a pretty slide that shows a logarithmic decline in customer found bugs per platform release 5->6->7->8->8.5->8.6.  Perhaps the definition has changed rather than the problem?

Cisco Unified Communications Manager Release 8.6(2) Deferral Notice
September 30, 2011
PLEASE NOTE: The Communications Manager (CUCM) 8.6(2) release has been deferred due to the following issue(s):
CSCtq94673

CUCM core dump when SIP phone deregisters during a call

In an attempt to fix a previous issue -- CSCto63870: Ò503 Service unavailable in station close state after SIP line resetÓ - wherein a SIP phone could become stuck in a de-registered state until CUCM was re-booted, our engineering teams inadvertently introduced a corner-case scenario in which a duplicate memory cleanup operation would result in the failure of the call processing module via an invalid memory de-reference (NULL pointer).

While this issue was only seen twice and very late in our testing cycle, we have determined that it is repeatable under very specific, timing-related circumstances and the result is the loss of system call processing until the primary call control module is restarted.

While the frequency of occurrence of this defect is low, its occurrence (and the occurrence of the original SIP de-registration defect) is unacceptable to us, as we know it would be to our customers as well.  We have quickly taken action to defer this release from our CCO download site and have halted customer shipments of this release until its replacement (8.6(2a)) can be made available.  While we cannot yet specify an exact date for availability, the expected schedule range for the posting of the 8.6(2a) release to CCO is: 10/10/2011 to 10/24/2011.

Cisco apologizes for any inconvenience this has caused our customers who are awaiting shipment or who have already downloaded the 8.6(2) release from our website.

Cisco Unified Communications Manager Release 8.6(2) has been replaced with 8.6(2a)

I read from a customer elsewhere that TAC had told them another release was coming Thursday. So soon I am guessing a show stopper bug and an "(a)" release?
