I think this looks just like the good old stuck in benchmarks bug.

Eric, could you unhide your hosts or give a link to this one. It would be nice to see the stderr from more tasks.


I just unhid them, the troubled machine is erb1 the others seem fine

I tried an experiment this afternoon and installed the Lunatics V8 MB executable just to see if that was going to have the same issue - and so far it hasn't. Of course its going to take several days to see this is really working but it looks promising after 6 hours or so on lunatics. One thing i do notice with lunatics tho and maybe its nothing but the estimated total time per work unit seems high most are 5 hours plus and some are 14 and a few are around 2 hours.

Switching to anonymous platform means the server has to relearn how long it takes to complete tasks for the application. It also happens when switching to a new application like the change from SETI@home v7 to SETI@home v8.
After about 10-11 completed tasks you will see the estimated time for newly received tasks will be lower and lower until it is accurate.

I would guess the 5 and 2 hour tasks are probably VHAR tasks or the the 14 hour ones are VLAR tasks.

And the lunatics version does not do function choice benchmarking meaning you got rid of the bug.

I noticed your host 7011730 that was having the issue looks to be running an older OS, Linux 3.11.10, than your two other machines. Which have Linux 4.1.2 & Linux 4.4.3.

Possibly an older lib somewhere mucking up the works for the stock app?

Yup, you are right, after 12 hours or so the estimated times dropped down to the normal 2.5 hrs I used to see. good to understand that now - tahnks

The normal kernel for OpenSuse 13.1 is 3.11 In my case, I updated the kernel on those machines myself. I have a 4.4 kernel I'm working on as time permits and will be switching to that on erb1 at some point down the road. erb1 got rebuilt/reformatted about 10 months ago or so because it had been through too many upgrades and things were getting weird there, so I did a fresh 13.1 install. (I tried 13.2 at that time too but I didn't feel it was really ready for prime time so I reformatted and went back to 13.1)

Everything is working fine now with the lunatics binary - so it appears to be a bug in the official v8 MB software, wouldn't you say? Although, I don't understand why it doesn't affect other machines.
Thanks for everyone's help with this issue - its much appreciated!

Either a bug or another limitation. As the error doesn't seems to occur with more recent distros. However a distro that is less than 3 years old I would expect to work. Unless there is a fault in something that requires being updated.
