RBR850 frequently issuing DNS REFUSED responses

Good Luck. This issue is resolved by the beta thats available.

I have inspected a litle further and with strace you could see tons of errormessages regarding read like this:
read(8, 0x166feda0, 272) = -1 EAGAIN (Resource temporarily unavailable)
where fd=8 is coming from the following call:
inotify_add_watch(8, "/tmp", IN_CLOSE_WRITE|IN_MOVED_TO) = 1
I guess the idea here was to watch for changes in resolve.conf and this might be a bug.
A lot of daemons logs to /tmp and making dnsmasq busy watching filecloses in /tmp
which result in the DNS forward request being "refused"
A workaround that seems to do the trick is to move resolv.conf to a less busy directory, in my case I created /tmp/dns/resolve.conf
and launched from commandline:
/usr/sbin/dnsmasq -h -n -c 0 -N -i br* -r /tmp/dns/resolv.conf -u root
No dns-errors after 1 hour running so fare
Running without errors for 24 hours now, so this seems to have fixed it.
I will send the information to them, and request for a bugfix. Propably is the "-n" --no-poll feature broken and the file-poll badly implementet.
