XMLRPC sync disturbs tinydns

[Andy_]

I'm operating a pair of 2.1RC1 (2013-08-06) routers which are syncing their config. Both have the dns-server package installed. When I change anything on the master machine (e.g. an IP alias), the dns server on the slave is reloaded as well; unfortunately, there seems to be some kind of restart problem because after the sync there are TWO svscan processes running on the slave, and tinydns isn't responding any more. These multiple svscan services will pile up until the service is stopped and restarted, which reenables tinydns on that machine as well.

I've been observing the stalling tinydns on the slave without any reconfiguration as well, maybe because there's some autosync? I enabled an event handler in my nagios installation that will perform the svscan restart automatically if needed, but this won't help if many config changes are performed in a short time; nagios will notice a flapping service and stop trying to fix the situation, manual restart is needed.

This problem persists since 2.0.1 up to the newest 2.1RC1 (just checked), and I can easily reproduce this by any config change.
