P6040 CoreStatus = 8B

[Oak37]

I picked up Project: 6040 (Run 0, Clone 129, Gen 31) which EUEd straight away with a CoreStatus = 8B (139). The client tried again and is currently folding the same unit with no errors so far. Has anyone else encountered this error?

There have been other reports of CoreStatus = 8B (139) from the a3 core but I don't remember if a cause (or a cure) have been found. Google on that string and you'll find a lot of posts on this forum.

I've had similar failures with the -bigadv a3 WU's (see below), but not on any other WU's - there's no mention of this on the FAHWIKI error codes - are we any the wiser on what causes these??

The CoreStatus = 8B (139) seems to be something of a Linux problem as it's appeared even on a Protomol single core WU.
