This error message could use improvement:

error: Traceback (most recent call last):
  File "/nix/store/y1yzy2zvs9cwina4jpj538x9cisn7g1g-nixops-1.6.1pre0_abcdef/lib/python2.7/site-packages/nixops/deployment.py", line 731, in worker
    raise Exception("unable to activate new configuration (exit code {})".format(res))
Exception: unable to activate new configuration (exit code 4)

Running nixops deploy multiple times resolves the problem, so it's likely related to memory usage.

exit 4 is returned from switch-to-configuration script when one of the systemd units fails during the config switch, you should be able to check that in the journal of the target machine.

Would be very nice if nixops gave feedback about the unit/service failure (show the journal log pertaining to the service)
