Hi all. Got an interesting problem while doing F18->F19b upgrade with yum distro-sync. Conseqeuences are already solved, I'm just curious about it and maybe it will provide some info to someone. The problem is that yum just freezed in the middle of update and I had to kill -9 it. Might be related to systemd cgroups point[1], but in this case warning should be more detailed and strong, as for me. The failed operation[2] was lauched at night under screen(1) with PWD=/root At the morning I saw it frozen on this (taken from the screen log): Updating : libreport-python-2.1.4-5.fc19.x86_64 769/3087 Updating : abrt-libs-2.1.4-3.fc19.x86_64 770/3087 cat: /var/tmp/abrt/oops-2013-02-28-19:49:04-663-1/uid: No such file or directory Updating : abrt-2.1.4-3.fc19.x86_64 771/3087 Machine state seemed ok—I was able to login on VT3 and kill yum with SIGKILL. All another methods didn't help: ctrl+c, ctrl+z, SIGTERM, SIGHUP, SIGINT,.. Yum process state was "interruptible sleep" in ps(1). Related syslog snippet is below[3]. Before this a similar upgrade on another machine was performed fine.
