Verify final result code for completed build operation
Build operation failed without specifying any errors. Individual build tasks may have failed for unknown reasons.
One possible cause is if there are too many (possibly zombie) processes; in this case, rebooting may fix the problem.
Some individual build task failures (up to 12) may be listed below.
