What does it mean ?
This message means that Tarantool did not write the end of file marker at shutdown, which it normally does. This can happen after a crash or hard reset, in other words, any kind of ungraceful server shutdown. The message as such is harmless, it warns you that some last transactions may have been not flushed to WAL since last start.
