Description

wpa_supplicant uses PF_ROUTE to return the routing table in order to
determine the length of the routing table buffer. As of 81728a538d24
wpa_supplicant is started before the routing table has been populated
resulting in the length of zero to be returned. This causes
wpa_supplicant to loop endlessly. (The workaround is to kill and restart
wpa_supplicant as by the time it is restarted the routing table is
populated.)

(Personally, I was not able to reproduce this unless wlan0 was a member of
lagg0. However, others experienced this problem on standalone wlan0.)
