- proxy/proxy.go: decrement connection count on dangerous path rejection (line 724) to prevent connection count leak - handler/sendfile_linux.go: return *os.File from getSocketFile and let linuxSendfile close it, fixing EBADF from deferred close in getSocketFd - proxy/websocket.go: return bufio.Reader from readWebSocketUpgradeResponse and wrap targetConn with bufferedConn to consume pre-buffered frame data, preventing first-frame loss - server/pool.go: use non-blocking send after starting new worker to avoid deadlock when queue is full - stream/stream.go: check stopCh on non-timeout UDP read errors to prevent infinite loop and shutdown deadlock - middleware/ratelimit: replace select-based close guard with sync.Once in StopCleanup to prevent double-close panic
