Except the memory issue only popped up when I started hostapd. When I
ran the same system as a station and wpa_supplicant, there were no
memory issues - just connectivity issues between wpa_supplicant and
Another issue that may be indicative of a non-hostapd issue is the flash
drive I'm using may be getting flakey as well (crc errors on loading the
kernel from a warm boot, for one).
At any rate, I updated the madwifi driver to the latest revision (r3065)
and it appears to have fixed the memory and connectivity problem - still
looking at some connectivity issues, but I'm still checking on that.
