Only one SSID on VLAN affected by storm, all others accessible

So this is a weird one I haven't experienced and hopefully someone can slap me with some knowledge.

This morning we had a network storm of some sort. I can see traffic when traffic increased on our switches, but not where. But that isn't the strange part.

Only one SSID seems to be affected. Other SSID's, on the same WAPs, on the same VLAN, on the same frequency worked fine. I didn't get a chance to wireshark the traffic because I could not get connected to said SSID to initialize the adapter for wireshark.

Does anyone have any ideas?
