It looks like virtual env had some performance issues, it took 90 seconds for cobbler to calculae sha1sum for a single file, here are cobbler logs:

Wed Jul 9 03:10:54 2014 - INFO | running: /usr/bin/sha1sum /var/www/nailgun/bootstrap/initramfs.img
Wed Jul 9 03:12:25 2014 - INFO | received on stdout: aed4173794ef758b9eaf2bff2413e6c88f5f640b /var/www/nailgun/bootstrap/initramfs.img

This was enough for astute to time out the task. Usually sha1sum calculation takes 1 second (or even less). So it looks like a temporarilly performance glitch on the virtual environment.
