After some years, I updated the Boinc-client und tried to get some work on my old Mac Mini.

Because VirtualBox is not installed there are only Sixtrack-WU allowed.

Every WU is running 0 seconds and is exiting with that errorcode above.

I dont' get why - is my Mac to old / or not suitable for the WU?
If that is the reason, why they are sent?

The stderr output from one of your results says

process got signal 11

Google that and you'll get lots of hits for example this one.

Hi, I made the executable you are using. It was built on the latest version of OSX. I see what you are running is quite old now. The executable is not fully statically linked, and has to pull in some libraries from the running system, so I think there is a miss-match here, and this is why you are getting the segfault.


In principle sixtrack should run perfectly fine on your computer. Would it be possible to build an executable yourself and use the anonymous platform mechanism? I can give you a guide on how to do this if you are willing to do so.

I got another error code for lots of my WUs: "1 (0x00000001) Unknown error code". Could anyone please explain what is it?

Could be a VBox kernel module that doesn't fit to your linux kernel.
This happens if you update your linux kernel and forget to run "vboxdrv setup".

BTW:
You may continue this discussion in an own thread as it only affects your VBox WUs (not SixTrack).

Because that Mini has not too much RAM, I reduced the allowed WU to one and closed Firefox (which occupies the most RAM).
That has not changed the problem.

I have another installation on another mac for steam, which does not support 10.6.8 anymore.
Under 10.11.6 and with more ram the WU runs so far...

So I will crunch there from time to time...

Many thanks for your help!
