WAP 321 Crash

fawiersch
Level 1
Level 1

Hallo,

I have a problem with four WAP321 at various locations.

All APs are configured with two WLANs and two VLANs.

The APs are connected via the Cisco power supply.

After about 7 days, the AP stops responding and you have to separate from the power supply. After the APs work again for about 7 days.

Resetting the AP did not change anything.

Problem with firmware 1.0.3.4 and 1.0.4.2.

crashdump with Software Version: 1.0.3.4


Crash Log:

Uptime of the AP: 7 Days, 0 Hours, 3 Minutes and 38 Seconds

CPU Unable to handle kernel paging request for process = swapper and pid = 0

epc == 800769c4, ra == c0519000

Stack Trace:
