Nice to hear that.

Did you configure both the WLAN ifname (interface=...) and bridge ifname
(bridge=...) in hostapd.conf? hostapd needs to know the bridge interface
name in order to be able to send and receive EAPOL frames properly. Feel
free to email a debug log file directly to me (j at w1.fi) if needed due to
message length limits on the mailing list.

If that happens constantly, no, I would not expect it. I do not know
what is triggered the disconnection based on this log excerpt, though.
Anyway, if you have not configured hostapd to rekey frequently, the
connection should remain up without any additional associations at this
