What Is Dat落ち?

Origin:2channel term. "dat" is said to come from the .dat file extension in which a thread's posts are stored, or from the name of the directory that held those files. Reference sources list several conditions that lead to dat落ち, mainly a long period without posts, and also a thread reaching its post limit or its log-size cap (about 512 KB). Dropped threads can be viewed in past-log archives. The first use of the term is not documented.
