Am using Unix folding appliance in VMware. It keeps downloading this and failing.

First try:

Second try gave me an error message in the console which for some reason was not copied to the log file. It said:

t = 0.000 ps: Water molecule starting at atom 570285 can not be settled. Check for bad contacts and/or resduce the timeset.

Got the same work unit. Immediate EUE, log error was "Client-core communications error" (8B). Was waiting a few days to see if anyone else completed it... thought I didn't see my client upload anything. Our errors are similar yet different. Console log:

I actually had this unit fail multiple times for different reasons.

[toTOW]

I found 14 reports of instant EUE for this WU ... but some one has been able to complete it.

[bruce]

Is it failing on overclocked machines? Maybe it's time for a new stability test tool.

[Grandpa_01]

Is it failing on overclocked machines? Maybe it's time for a new stability test tool.

Or may be it is time for Stanford to realize there might be a slight bug in there client or WU's and fix it. That would be better than the dumping method.

[BigJohnFAH]

... but some one has been able to complete it.

Then why did I get it ?
Currently at 18% on this one. I guess this will test my OC.

[Wrish]

Update: Despite claims that someone completed 2684-6-1-0, I was reassigned this unit yet again today, twice in a row. On my second attempt, it EUE'ed in 3 seconds like before and uploaded 13251 bytes to the server. On the attempt immediately following - my third - my CPU began folding it successfully (past 2% now). All I can think of is that the third attempt did not immediately follow an A2 bigadv folding session like the ones before. Or, considering the different errors each time, maybe I rolled a compatible number on my random number generator... assuming the workload is not deterministic.
