Anyone ever seen this before? It's a new one to me. FahCore killed itself with WU_STALLED result and then restarted, picking up at the last checkpoint.

CPU slot on a system I just put into service recently... does this indicate instability?

Do not normally run cpu wu, but "unknown error code" could be anything, from hardware to faulty wu. The messages in the logs are not very informative. If it looks like the project wu is the issue, would be good to post info at the folding forum.
Just curious... again, never seen that result code before. I'm still not used to the way v7 will retry multiple times if the FahCore exits before completion of the WU.

WU completed and was uploaded with a good WORK_ACK so I guess all is well.

HFM handled it fine and kept on trucking with the retry and completion so it's not a situation I'm convinced I need to observe with HFM... but I'll keep my eyes on it.
I've gotten that type of error before on GPU's

I's not exactly a stalled WU but it does the same thing.
