[Dnsmasq-discuss] ubus problem

[e9hack]

Hi,

I'm using the latest dnsmasq version with openwrt. There are two instances running. One provides dhcpv4, dhcpv6 and dns
to several networks, the other one dhcpv4 to one network only. It looks like, that the second instance has a problem
with ubus:

Sometimes, the starting sequence is inverted. The error occurs all the time on the seconded started instance only.

This occurs since this commit:

Improved UBus supported
