When I over-drive ath10k station using pktgen, system goes OOM quickly. If I catch it in time and stop pktgen, then memory is recovered over the next few seconds. I assume that there is an un-bounded queue somewhere. But, I cannot find any queues in the mac80211 tx path that apply to ath10k (as far as I can tell). The one possibility is the pending queues, but printing them out with debugfs shows them all zeros, and I have some code to bound them at 1000 pkts anyway. I didn't see anything obvious in ath10k either, but I must be missing something... pktgen transmits under the queue logic, so it will likely be ignoring any queue-stopped signals from mac80211. Are there any other places that pkts can be queued()? Thanks, Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com
