I was reading error 4305 in this forum, but I think the situation from original post (spanish) is different. The problem is: Recovery model: Full. Transaction log backup: each hour. Log Shipping without problem. When she (Nuria) run reindex and after that she truncate the log, she has 4305 error. Because lack of space she has to truncate that log, and so there is a gap. That gap cause 4305 (this is my conclusion). What do you think about the best way to fix the problem? (I have no experience with log shipping).
