To Reproduce

running cnspec scan on photon 4

Expected behavior

scan should just run through

commented

First attempt works:

Scanned 1 asset

VMware Photon OS/Linux
    C photon-minimal

It's Photon 4 as a Vagrantbox.

commented

I enabled both levels of the DIL policy, but still no panic.

If we get the full cnspec debug log we can see which query was being executed at the time of the crash. This may help narrow down the root cause

commented

We close this for now. If that reoccurs, lets collect the mondoo-debug-* files with:

DEBUG=1 cnspec scan local
