I have had a few of these myself.
It appears that when the WU restarts from a second checkpoint the "seed" value changes and this then makes the WU invalid.
After a restart from the first checkpoint all is OK, but from the second checkpoint on the seed value changes for some reason.

I have a grad student working on this issue right now. Hopefully he'll be able to figure it out soon.

This problem is still happening with the latest DNA work units
See WU 4793428

I will get Zero credit for this work unit when a third WU is processed by someone as the 'seed' value has changed on my WU.

Yeah, I've been trying to get the DNA@Home grad student to fix this! Will try and bump it up the priority queue.
