Karma Log Question

[pdb1977]

So i was checking out the Karma log.

There is an entry (actually more than one) that says:

Dec 20 14:00:00 KARMA: Checking ESSID ABC against XYZ. - I know ABC is an AP, cause its mine, but i also know that XYZ is another AP.

Why is Karma checking one AP against another AP????

Also for clarification does:

EESID = AP host name and

BSSID = AP MAC address??

Thanks guys
