Добрый всем!

Ситуация такая: имеем веб-сервер, сервер после ресайкла, BLT linq запросов ещё не исполнял (использую DataContext).
Делаем к нему 2 запроса (которые внутри используют BLT linq). Ревизия 1060. Потом когда все запросы уже отрабатывают быстро — у меня повторить неудаётся (возможно просто не успеваю).
Так вот один из запросов отваливается с таким вот сообщением:
Мне кажется что-то подобное я уже видел но в упор не помню где...

Либо другой экзепшн (когда какой не понял).
Разумеется никаких колонок obyn1 у меня и близко нету, по крайней мере в тех запросах которые успешно генерируются...
