I'd like to reproduce this myself at least once, I left iperf running over night with no rants from SLAB. I should note this should be reproducible with RX only if it is ath_rxbuf_alloc() to blame but without a concrete reproducible instructions it is hard to guess what to do and if this can only come up during RX. Can you describe a little more when you have seen this? What were you doing exactly, for how long? When was the last time you saw this, what were you doing then? Luis
