local dnsmasq on APs not working after reboot until dnsmasq is restarted

More often than not, after AP is rebooted, local dnsmasq is not working until killed and respawned. Interesting thing is that I have 7 APs, a mix of old UAPs and new UAP-AC and UAP-Ac-Lites and it does not happen all the time on all of them, but it is getting worse, now its one out of 10 reboots it comes up OK without restarting dnsmasq.

 

 

example:



alex@staff:~$ ssh support@192.168.2.186 reboot

(2 mins wait until it reboots)

alex@staff:~$ dig google.com @192.168.2.186

; <<>> DiG 9.10.3-P4-Debian <<>> google.com @192.168.2.186
;; global options: +cmd
;; connection timed out; no servers could be reached
alex@staff:~$ ssh support@192.168.2.186


BusyBox v1.25.1 () built-in shell (ash)

Welcome to UniFi UAP-AC-Lite!

FirstFloor2-BZ.v4.0.42# pkill dnsmasq
FirstFloor2-BZ.v4.0.42# Connection to 192.168.2.186 closed.

alex@staff:~$ dig google.com @192.168.2.186 +short
172.217.18.110



 

 

As mentioned I have 7 APs, all are on the latest firmware (v4.0.42.10433) , except one of them is on 4.0.14.9736 and that one is always OK. I have rebooted so many times to try to pinpoint the pattern, but I can't find any.

 

Any suggestions on how to debug this further are appreciated

There's a solution for this in testing - it's a now known issue (this was discovered thanks to feedback from 4.042 public release).

 

More soon!
