The condition work_available(&conn->work) && tx_unacked != 0 prevented tcp_update_retrantimer from being called when the work queue was still busy, leaving conn->timer stale or zero on subsequent sends. This caused the RTT estimation to compute a false RTT (m = rto - 0 = rto), creating a positive feedback loop that inflated the RTO to extreme values (e.g., 232 half-seconds = ~116 seconds). Fix: remove the work_available check so that tcp_update_retrantimer is always called when there is unacknowledged data. The decision to re-queue the work is handled internally by tcp_update_timer.
