Just a guess - but maybe the build has exhausted the builder's
memory? If so, you might be able to workaround it by restricting the
parallel level. I can't offer an explanation as to why it started
occurring with this upload. Assuming nothing about the builder memory
config has changed, you might need to compare memory usage profiles w/
an older build environment to look for red flags.
