Although many of these warnings can be an indication of problems, this happens 
sometimes. If it's just happening occasionally and Reaver keeps going 
afterwards, it's not a big deal.

If you use -vv instead of -v here is what I expect you'd see: when attempting 
pin 40905679 the first time, the WPS transaction does not properly complete (a 
packet probably got dropped/corrupted somewhere) and Reaver terminates the WPS 
session in order to try the pin again. After this, the AP does not respond to 
EAPOL START and/or EAP identity response packets, probably because it did not 
honor Reaver's request to terminate the previous WPS session. Reaver keeps 
trying to initiate a new WPS session though, and eventually the AP's stale 
session times out and it starts accepting new WPS sessions, at which point 
Reaver can start trying pins again.
