Steps to reproduce: export BB_SERVER_TIMEOUT=10000 bitbake core-image-minimal ctrl+C before it finishes change something in local.conf (for fun, try changing MACHINE) bitbake core-image-minimal Result: Parsing is skipped, and lots of task mismatch errors. In the case of changing MACHINE, you will likely get multiple task mismatches for every package built.
This has been open a long time and there were many fixes in this codepath. I did try and reproduce and it seems to work now so resolving as fixed.
