ARIA	5cfadb4d9b	fix: set SO_REUSEADDR on port pre-check so restarts don't wait for TIME_WAIT The fail-fast port check bound a plain socket, so TIME_WAIT sockets left by a just-stopped instance (~60s) made it report 'port already in use' even though uvicorn (which sets SO_REUSEADDR) could bind fine. Mirror uvicorn's bind semantics: the check now only fails when the port is genuinely held by a live listener.	2026-10-03 21:18:22 +02:00

fix: set SO_REUSEADDR on port pre-check so restarts don't wait for TIME_WAIT

The fail-fast port check bound a plain socket, so TIME_WAIT sockets left
by a just-stopped instance (~60s) made it report 'port already in use'
even though uvicorn (which sets SO_REUSEADDR) could bind fine. Mirror
uvicorn's bind semantics: the check now only fails when the port is
genuinely held by a live listener.
