Yes. the problem started with v4.1.171.0 after about one year of
stability on the dos/arp storm workaround. We use stand alone 4402. DHCP
is set as required. We are only using lwaps. I looked at v5.0 as
documentation that seemed to suggest resolution for most of the known
bugs -then found out that release was not compatible with our 1000
series ap's. prior to install. Cisco engineering also suggested waiting
to deploy that release but that was mute due to the hardware incompatibly.
Only one full controller crash generating a log. The system hangs
preventing authentication and existing authenticated users are impacted.
Seems like a denial of service between the clients and ap's but that was
supposed to be fixed after 4.1.171.0. I have tried several configuration
changes and have a couple of tac requests in process with cisco.
What are you experiencing ?

Hey Steve,
Curious as to those high load hangs. We're running 4.2.99 on several
WiSM-based controllers. What's the symptom? Do you have to reboot
the controllers?
Thanks,

Hi Peter I have been experiencing high load hangs on v 4.2.099.0 and
wanted to migrate to V5.0 for more stability.
However v5.0 is not compatible with Cisco Aironet 1000 Series Access
Points. "The 1000 series access points are not supported for use with
controller software release 5.0.148.0". Must use 1130 series AP and
above. It looked like there was no planed improvement to the 4.x code
leaving many of us with a large and */costly /*legacy system in place.
I thought that ought v4.2.099.0 to be the latest code you can run on
the Cisco 4400 standalone controllers with 1000 series access points
however, I just noted that on March 17 v4.2.112.0 is released. Nothing
above v4.1.185.0 is assure ware certified however. I am now looking at
v4.2.112.0 trying for more stability...

5.0 as we are considering upgrading.
