Why through batch resizing via jpegoptim - not all files are processed?

Question

Debian

Good afternoon!
Resizing via command from jpegoptim
find . -name "*.jpg" | xargs jpegoptim -m50 -f ./compressed -p
Some of the files are resized, but some of the LARGE files are getting ERROR:
1-4-klassov.jpg [ERROR]
It's not clear why. Can you tell me how to fix this?
Thanks
