450i AP [in]stability with RADIUS?

I'm running our first 450i AP in the office for a test AP - I'm trying to build code to automatically assign and track all IP addresses. One of the planks in this approach is to use RADIUS to hand out the SM Management IP, but I'm having a heck of a time trying to get this AP to simply not crash every 5 minutes if the Authentication Mode is set to Radius AAA.

I saw that the latest Beta f/w reportedly fixes  a  "Memory corruption bug fix for RADIUS", but it even with 14.1.2 Build 4, the AP just keeps rebooting every few minutes. Change the security mode to "Disabled", and it's happy as a clam, not rebooting at all in 16 hours. Back to RADIUS AAA, and 6 minutes is an impossible goal.

Is the Cambium team aware of this? Are they still working on it?

The event Log is filled with this sort of mess...

Hi, Can you please disable ‘Accounting’ from Accounts → User Authentication And Access Tracking -> Access Tracking Configuration and give it a try.?

OK, that works. As we aren't yet relying on RADIUS accounting, it's a workable solution.

We have fixed that issue in next beta build , it will be out soon.
