HiQ put and HiQ get

Does anyone know what these are? I’ve looked all over and cannot find any definitions or explainations. The reason I ask is I have a 5.7 360 degree cyclone that has a enormous amount of both, the “HiQ put” and “HiQ get”, logged in the scheduler tab of “statistics”. These are in the millions and are the only statistic that looks out of place. This AP will reboot every-so-often. After the reboot everything is fine. I would just like to know if these are causing the reboot and why. So, if someone knows what the heck a “HiQ put” and “HiQ get” is please enlighten me. Thank you in advance.

Just a little more info, the AP is running ver. 8.1.4.
