qubes-dom0-update --clean exits unexpectedly

[lunarthegrey]

Qubes OS version:

Qubes Release 4.0

Affected component(s):

qubes-dom0-update

---

Steps to reproduce the behavior:

Run this in a dom0 terminal: sudo qubes-dom0-update --clean

Expected behavior:

Yum cache is removed successfully.

Actual behavior:

Says that files were removed, then looks to be syncing repo-data. After a short (sometimes long) period of time you get an error and the process will be killed like:
/usr/bin/fakeroot: line 181: 9686 Killed FAKEROOTKEY=$FAKEROOTKEY LD_LIBRARY_PATH="$PATHS" LD_PRELOAD="$LIB" "$@"

General notes:

Seems to only happen when running sudo qubes-dom0-update --clean

None that I know of.

What VM you use for UpdateVM, default sys-firewall? What template it has, default fedora-26?
Do you see anything related in journalctl -e in that VM?

@marmarek I currently use sys-firewall and it's running off the default fedora-26 template. Thanks for the suggestion about checking journalctl. I actually found that it was OOMing and that's what caused the process to die. Once I gave more memory to sys-firewall the issue doesn't occur.

I kind of forgot how update VMs worked...
