M1 MacBook Air w/1Tb SSD running out of disk space

[AusS2000]

I have an M1 MacBook Air with 16Gb RAM and a 1Tb SSD and about 300Gb on it. Monterey 12.6.

I am periodically getting messages that I am running out of drive space and when I check it I'm at 990-odd Gb.

A restart brings it back to 300-odd but after a period of time it kicks up a fuss again.

It's clear the system is using the SSD for some sort of cacheing and not clearing it periodically.

Is this a known situation? Anything I can do about it?
