Controller / Prime error STATION_BLACKLISTED moreRecentEventsQueuedAction

[patoberli]

Hello

I recently discovered that my Prime Infrastructure 2.2.2 shows this error message for one of my controllers (the one with the most AP connected to it):

STATION_BLACKLISTED moreRecentEventsQueuedAction trap/event dropped
because multiple io requests queued for same instance

I couldn't find any information to this error message.

Anybody an idea what I could/should do here?

Thanks

Patrick
