Yes, we can investigate this. But it may not be feasible - at least the level of support that can be available outside developer's office hours would most likely be just basic infrastructure support. 

It should be noted that we have been (and partially still are) in the process of being separated from the Digia group. While the CI part was mainly done months ago, there is overall a lot of issues ongoing that stretch the capabilities of IT personnel. That is of course no excuse as such, but an item to note anyways.

Or at least we should make sure disks that are not automatically cleaned, are cleaned in advance during the office hours. I do agree with you that running out of a disk space should not be a reason for CI failure - and mostly it has not been, despite you hitting that over the weekend.
