Hostapd disconnects clients

[ravin goyal]

Hello, I have an banana pi m2+ running raspian lite 3.4.112-sun8i
I am using using hostapd-1:2.3-1+deb8u4
I have managed to configure and run successfully on my wlan0 interface
and for that I have to do

modprobe -v bcmdhd op_mode=2

command before starting it.

I am able to connect to the AP and it works well but after sometime I
noticed in syslog that it disconnects my connected client and following are
the messages which i noticed in syslog when it disconnects client and
afterwards.

I tried to connect again but device failed to connect and when i restart
the hostapd it starts and connect to the client automatically
strange ?

I am not able to understand the errors in syslog and what have i done wrong
here?
Can someone please help me on this?

link to the hostapd conf file

And worse is that I sometime faced kernel crash in the middle when hostapd
is running.
