2.9.51 wds connections causing lots of CPU usage?

I’ve only tested this for 3 versions,

2.9.51, 2.9.46, and 2.9.35


I have a Rb133, rb532 and a wrap 2.e


All seem to show a lot of cpu usage (above 60%) even when there is no traffic. Ive found if I disable the wds interface on any of these the Cpu usage goes down to about 8%.

However my routers with exact same wds settings (just different location ect. ) with 2.9.35 don’t show this unusual CPU usage. 2.9.46 ad 2.9.51 DO.

anyone seeing this?

tks
