re-authentication with hostapd

[mohamed ali kaafar]

i'm using hostap, xsupplicant and freeradius for authentication. setting the session time,
 the re authentication failed with hostapd, while it's runnig correctly with a material AP
  (cisco 350 series). what's the problem? is there anyone in the group who can help me??
   here is the hostap log

Ps: if i reconnect the client to the hostapd with iwconfig , the re-authentication continue correctly, is there a way to avoid this?
