That message, and ones similar to it, indicate that SD's scanning process wasn't able to start a new scan batch (i.e., a single fetch from the SE API and scan all questions and answers returned from that fetch) for longer than generally expected. It can indicate that there's one or more messages within the current batches which are taking an unusual amount of time, but might also indicate that there were multiple watch/blacklist changes within a single scan fetch (or within the number of scan threads which that SD instance can launch). It's
significantly more likely to happen when the SD instance is first becoming active, as the instance won't have any posts in its recently scanned posts record, so is scanning all posts which it fetches from the SE API, rather than skipping any that were
unchanged from when previously scanned.
