It's not just Morty. I have had this issue with other releases and on Master. In my cases, the issues tend to be limited to building on laptops. I have not seen this on towers or servers. Try tuning your build to reduce the number for cpus and threads used. see PARALLEL_MAKE and BB_NUMBER_THREADS. - armin > > Joshua Watt > -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
