One of my dedicated folders is having a problem with Project: 2665 (Run 1, Clone 649, Gen 6). It immediately dies with a CoreStatus = 66 (102), which is the "Shutdown requested by user." I did not, of course, attempt to shut it down. I also see in the syslog that 3 of the 4 cores segfault at that time. It has done this multiple times. As I would love to get past this WU and get this folder folding again, I'll try to dump it, but wanted to report it first.

System is Ubuntu 8.04, Linux 6.02beta1 client, q6600@2.88GHz, 2GB mem.

ok, thanks, i'll try and remember to check if anyone else is able to return the unit. If you get assigned the work unit again later with similar results please let us know!

Same thing here. After 4 tries yesterday, I finally got another WU, and after finishing it, I'm back to this one: 2665 (Run 1, Clone 649, Gen 6), which does this:

I had a Quad machine running Ubuntu that got stuck on the same work unit today. P2665 R1 C649 G6
It would segmentation fault before it even started, and then just shut off Folding. I'm not sure how long it sat there doing nothing before I found it.

Also, because it did not EUE or some other defined fault, evey time I restarted Folding it would restart the same work unit. I was forced to dump out the work folder and queue several times until the Folding was issued a different work unit.

OK. Thank you, I will notify the researcher in charge of this project of your report.

I've already reported this on one of my machines. I came in this morning and another machine has this same WU, with the same result.

It'd be okay if the machine could dump it and start over, but it requires a manual restart. It's bad enough that the points suck on the 2665s but this is just adding insult to injury.

Tried four times to get it to run.Thats all that happens.
Tried moveing it to a different computer. Same result.
Deleted it and grabbed a different protien.
I've saved the work folder and queue.dat file if that helps.

Luck ............

This appears to be a bad WU and has been previously reported (see http://foldingforum.org/viewtopic.php?f=19&t=3513). Too bad it is still in circulation...

thanks, looks like it indeed might be a bad WU, its not always easy to tell... i'll pass it along to peter right away who's monitoring the project...

Posted: **Mon Jul 14, 2008 7:17 am**

thanks guys!

Posted: **Mon Jul 14, 2008 1:49 pm**

I see some people that were able to return that WU, but they all got partial credit for it ...

Posted: **Sat Jul 26, 2008 3:07 pm**

And all this time later, yet another of my machines gets this same WU, with the same result.

Posted: **Sat Jul 26, 2008 10:24 pm**

Same symptoms as above, 2665 (Run 1, Clone 649, Gen 6) on linux 6.02 release client. (Gigabyte GA-P35-DS3P mobo, Q6600, 2.6.25-gentoo-r6 kernel)

After multiple runs ending with error and segfault, I try `./fah6 -delete <work_unit_number>` but fah6 just seems to hang doing nothing, does not delete work unit. Ctrl-C and SIGTERM do not end 'fah6 -delete..' processes but SIGHUP does. Move queue.dat, work directory, FahCore_a1.exe to fah_debug directory (effectively delete them) but keep getting same unit assigned and having it immediately die.

Finally end up starting fresh with only fah6, mpiexec, and client.cfg; up and working again.

It looks like sooner or later, I'm going to report this WU for every one of my machines.

Add another one to the count....

Which is apparently the goal. Add yet another one to the list. This makes 5 of my machines that have gotten this WU. I reported this WU on 06/26. If I've now received it on 5 machines in two months.... well never mind, it's obvious Stanford is going to continue circulating this WU ad infinitum.
