You're probably using a 64 bits system. Version 1.0 of CMS is supported only for 32 bits environments, unfortunately, due to some limitations of the sandbox program used. See for some more reference: http://cms.readthedocs.org/en/v1.0/Running%20CMS.html#recommended-setup If you can, our recommendation is to reinstall the system you're using for your contest and put Ubuntu 12.04 LTS with 32 bits, which is the best tested environment. If not, you can use the tricks explained in the link above to setup a 32 bits chroot and run Workers there. If you just want to test the system, it should be enough to replace: sandbox.allow_syscall = ["waitpid", "prlimit64"] with: sandbox.allow_syscall = ["prlimit64"] in cms/grading/__init__.py. This is highly discouraged for real contests. Hope this helps. Feel free to ask again if you don't manage to fix!
