(In reply to Kevin Bowling from comment #24)

Indeed, when it gets an ENOBUFS back, RACK will start pacing the connection.

                 * Failures do not advance the seq counter above. For the
                 * case of ENOBUFS we will fall out and retry in 1ms with
                 * the hpts. Everything else will just have to retransmit
                 * with the timer.
                 *
                 * In any case, we do not want to loop around for another
                 * send without a good reason.
