こんにちは、けんずふぁみりーです。
FreeBSD 8.1-RELEASE apache22+proftpd+bind
一部の機種で再起動時にproftpdが起動できないので
いろいろ切り分けをして見ましたら。
/etc/rc.d/named の冒頭に
sleep 1
として起動のタイミングをずらすと問題が無くなりました
いったいどんな理由からでしょうか？
もっとスマートな解決策はありますか？
通常の設定でproftpdがこけるときのログ

またこの問題は沢山設定してあるsleveのゾーンの内特定のひとつだけを削除す
ると回避出来ます。そのゾーンを設定したままでもmastaからゾーンをもらって
いない状態のとき（初めてbindを立ち上げる時）は問題がおきません。
全く同じ設定を別のマシンでも再現しましたが問題はおきませんでした。
その別のマシンの正常なログ
