There should be a config option to direct it to use a more voluminous volume.

In the printout at the end of job, shows we still do have space around, just not in /tmp

This is /tmp inside the container, if I understand it correctly, not the /tmp on the host system. Too bad, because looks like our rocm images are again too big to scan, in that case. Some space saving measures need to be found.

[jiridanek]

Possibly mount /tmp as a compressed volume ;P
