Did you check what /tmp inside the container show?

My guess is that your container mounts its own tmpfs on /tmp, which would
be limited to half RAM by default. Configure your container (inside the
container, not from lxc config) NOT to do that, and /tmp should have the
same available space as your container rootfs.

Another possibility is ulimit issue (i.e. the problem might not be with
space, but with number of open files). Since you use privileged container,
you can adjust it inside the container before you start the proces.
