blocked state; closed state
Technical computing term for a state where a process, port, or resource is blocked or closed.
If the port is in a blocked state, communication is not possible.
閉塞 is the core noun meaning 'blockage' or 'obstruction'; 閉塞状態 specifically refers to the state of being blocked, often in computing contexts.
Compound of 閉塞 (blockage) and 状態 (state). The exact historical derivation is uncertain; the spelling is conventionally associated with the meaning.
