Example of a successful gate job that only failed on the last few steps in toci_quickstart.sh:

This is the problematic line: https://github.com/openstack-infra/tripleo-ci/blob/701ff27cfb11897a0c998ea6d3556fa94bfd5634/toci_quickstart.sh#L109

My suspicion is that the sorting happens in the /tmp directory which could get full (or has some other problem?) and the sort operation fails.

Possible solutions are:

* using `sort -T <dir>` and point it somewhere where there is more space.
* reduce the amount of files that we check by using `du -d 1` for example
