Is there a know bug with multi-threading and the RB450Gx4? I have an issue where on two of these routers it seems to get stuck processing everything on pretty much one core (core 3). A simple reboot of each router seems to fix the issue and load is more evenly distributed between all the cores.
One router is 6.47.7 and the other in the photos below is 6.49.5.
This router is used as a router for one of our Airmax towers. Router was passing around 300-400Mbps to around 280 clients before and after the reboot.
