NetworkManager stops and starts dnsmasq very frequently (every few minutes). During the brief window that dnsmasq is restarting, hostname resolution doesn't work. dnsmasq is getting restarted frequently enough that I see brief hostname resolution errors in Chrome several times a day during normal web browsing.
This is on Precise with network-manager 0.9.4.0-0ubuntu4 and dnsmasq-base 2.59-4.
The frequent restarts seem to be triggered by IPv6 route advertisements on my network. (See log snippet below.) When NetworkManager gets a route advertisement, it reconfigures everything. In the case of dnsmasq, this means stopping dnsmasq, writing a new config file, and starting dnsmasq. NetworkManager should restart dnsmasq only if it its configuration changes.
I'm attaching a snippet from /var/log/daemon.log on my system that demonstrates a restart. This is with debug logging configured in /etc/NetworkMan
