Xorg.0.log stuck, never stops

[Gene Heskett]

Greetings all;

Specially built preempt-rt kernel running an 11x56 metal lathe from 
an rpi4b, armhf flavor. Uptodate except for locked kernel.

I just noticed my Xorg.0.log is growing, probably will continue to grow
untill the 64GB card is used up, adding this stanza every few minutes:

Video looks great. Any idea what the problem might be?

Thanks.
