More testing! :) See if turning off and turning on the captive portal fixes
it. If so, you can script it to go off and on overnight and minimize this.
Also, longer idle timeouts can lower the load. But let's be sure it is the
captive portal first.
I guess that is the only thing to do. Thanks for the tips :) Happy New Year
