Controllerless Networks

Hello,

Starting a few weeks ago all of our APs except for one have started to reboot every 4-5 minutes with reboot reason "Kernal Panic: Out of Memory". We worked with support to RMA all of our AP-315s (JW813A), and had them replaced with Brand New AP-315s. These APs exhibited the exact same issue directly out of the box. All we did was take them out of the box, peel off the plastic, and plug them in. We've been working with Aruba support, and over the course of several 3+ hour calls we have only managed to break the last working AP, and solve none of our issues. We have tried the latest firmware on 8.11, 8.10, 8.9, and 8.6. All of which exhibited the same issue. We have tried plugging the APs into different switches, different power sources, and even using a different VLAN. Hard resets have done nothing. We are at the end of our rope here, and actively looking to replace Aruba with a different vendor so that we can supply our users with WiFi again.

Any ideas would be appreciated.

Thanks

Strange that support RMA-ed the APs for an out-of-memory problem, as the replacement AP is supposed to have the exact same amount of memory. What is more likely is that you have a specific feature turned on that introduces a memory leak in one of the processes running on the AP. And TAC should be able to see where memory is going and what is taking up the memory. You could even do that yourself with the 'show cpu details' and 'show process' commands, and compare that over time. Another thing would be to disable any feature (not used) except that basics and when the memory leak is gone start turning on again.

Please work with your local Aruba SE to get assistance with your TAC cases, without knowing the further context, the approach chosen doesn't sound right. Asking TAC for escalation in your case may help as well.
