dawn seems to freeze

[ff-mgk]

Hello, i hope I haven't overlooked an present issue.

I am using 6 dump openwrt-APs, each with 3 uniformly SSIDs. 1 SSID ist open (Freifunk), 2 SSIDs are WPA2-PSK+802.11r. All 3 SSIDs appear in dawn. I wonder why, because an open network does not correspond to 802., but ok. I am Using 2.4 + 5 Ghz --> there are 26*3=36 wifi-networks

2 APs are Xiaomi Redmi Router AX6S aka AX3200 OpenWrt SNAPSHOT r19592-4509b790f0 / LuCI Master git-22.119.37097-531c0ec dawn 2022-01-17-7a726740-1 luci-app-dawn git-21.282.29102-4a78122

4 APs are Xiaomi Mi Router 4A Gigabit Edition OpenWrt 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-22.083.69138-0a0ce2a dawn 2022-01-17-7a726740-1 luci-app-dawn git-21.299.23946-ae446ce

hint; the last Line does not repeat, the log stops

Since now i was too slow to catch the beginning...

I have command in cron: /5 * ubus call dawn get_network || service dawn restart

[ff-mgk]

/5 * ubus call dawn get_network || /etc/init.d/dawn restart

is more comfortable for use with cron

Can you update on latest dawn version and test again?
