We were testing with 64 virtual stations running WPA, with
a single instance of supplicant controlling all interfaces and
the scan-sharing enabled. It was running clean w/out encryption
(and w/out supplicant).
We see a large number of these types of warnings. We had a proprietary
module loaded, but it was not in active use. We're going to reproduce
without it, but in the meantime, here is a representative trace:
