i "think" some of devices in your network are entering into power save mode when actually they r not in that mode..

hmmm thanks, wish Ruckus rep could confirm this. 

I've gone to Engineering to understand where in the code this message is invoked.
They say it identifies out of range parameters in some values processed for client power-save.
And while harmless, they will make a correction to prevent display of this message.
