It runs PDFLaTeX repeatedly hence the repeated error messages.
What I do in these cases is
lyx -f -e pdflatex file.lyx
Then run
pdflatex file.tex
(preferably from TexTmate2 on the Mac with Command-R) and go to the
lines generating the error messages.
If I can figure out how to make it compile without error I try to
figure out how to fix this in LyX.
If all fails, remove EVERYTHING (text before and after, formatting and
loaded packages) step by step, until the error goes away. then generate
a very small file (Minimal Working Example) that produces the error and
post this here.
