Comment (by Vikram):
I have noticed this in the r1454 release. The problem does not occur righ
away, but after sustained traffic exchange. Not sure if it existed before
that. I set up ad-hoc mode in three boxes and run netperf in some
combinations. I did this two different times, and the following type of
error occured (as extracted from /var/log/messages). I have also posted in
[http://madwifi.org/ticket/334]
Notice the "ath_uapsd_processtriggers: no skbuff" message was then
repeated numerous times; although it says that mysql was terminated. The
other machine terminated more programs including mDNSResponser, xfs, X,
sendmail, and others
