Hi Trevor I am seeing a failure on qemux86 on ubuntu 22.04 host and its fairly regular.
https://errors.yoctoproject.org/Errors/Details/729506/ it seems rpmdeps is crashing with signal 9. I wonder if its something to do with rpm changes we might have got in core but, I can confirm that it was not an issue two weeks ago. It worked ok on Jul 17th but broke on Jul 27th CI builds.
