Looking at the relation count, I think this is where you were, h, one more sieve block might have done it......looking back at similar sized jobs, mine needed slightly more relations than you had.

Probably not fail, maybe just need a few more relations than usual. It'd be interesting to see if other folks have had any problems with 50/50 splits on their jobs.

Maybe the solution is to keep 1.39 around as a fallback if there are similar problems in the future.
