I haven't been able to reproduce hostapd freeze.
However, I after some two hours stations deauthenticate with hostapd and they
do not authenticate again even when restarted, I need to restart hostapd.
I have attached hostapd log file with station trying to reauthenticate after
I have also two hours long strace log, tcpdump, hostapd_cli and iw dev wlan2
I can put it on the net if anyone would like to check what is going on.
