[8.202-8.300] DNS (named) stops working

Hi,

Upgraded from 8.202 to 8.300 on one of mine fw's on 25th january.

After this I've been unable to get DNS to work. Checking the logs it seems named it exiting the same second it starts.

2012:02:07-19:57:38 172 named[10513]: built with '--prefix=/' '--sbindir=/usr/sbin' '--with-openssl=no' '--with-libxml2=no' '--without-kame' '--without-idn' '--disable-libbind' '--enable-ipv6' 'CFLAGS=-march=i686 -mtune=i686 -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables'
2012:02:07-19:57:38 172 named[10513]: using up to 4096 sockets
2012:02:07-19:57:38 172 named[10513]: Using 101 tasks for zone loading
2012:02:07-19:57:38 172 named[10513]: loading configuration from '//etc/named.conf'
2012:02:07-19:57:38 172 named[10513]: //etc/named.conf:106: zone '.com': is not a valid name
2012:02:07-19:57:38 172 named[10513]: loading configuration: failure
2012:02:07-19:57:38 172 named[10513]: exiting (due to fatal error)

And this happens every 30 seconds.....

Is this a "common" thing with 8.300 or am I just lucky?

Will do a reinstall during the next couple of days if I don't find a fix.
Need my Site-to-Site back online, and that needs DNS...

Best regards

Vegard
