Spectral Scan issue

Hello
When I do spectral scan with less than 128 samples the device CPU gets 100% loaded and device fails with out of memory in ~10 minutes
Command to reproduce
/interface wireless spectral-scan range=“2.4ghz” samples=100
All devices with mipsbe affected with any router OS (7.12 and 6.49.10 versions of RouterOS are affected for sure)
