Can changes be made to banned IRQs without restarting irqbalance in RHEL 6.4?

Solution Verified - Updated -

Issue

After IRQs are banned by adding --banirq=XX to the config file /etc/sysconfig/irqbalance the command pkill -HUP irqbalance is run. This does not appear to work.

Does irqbalance need to be restarted to add additional IRQs to the list of banned IRQs?
