Hi, Possible that you have got a different cron implementation. There is no hidden info in our bugzilla; the reproducer is using lvm commands, but I remember it worked with any command. Actually its not about the warnings, a "cat" will probably also do, if you check its /proc/$pid/fd when its invoked. But cat doesnt emit warnings about open fd's. Not sure about upstream, probably not. regards, Sebastian On Tue, Jan 08, 2013 at 09:01:19PM -0700, Vincent Danen wrote:

I'm trying to reproduce this in Fedora and RHEL using lvdisplay (maybe a bad choice?) and also using "lvm vgck -v vg_thor && lvm pvs" in /etc/crontab. The output is mailed to me fine with no warnings? Can you share what command was being used to reproduce this? It's possible that something you added (or we added) makes this a non-issue on other platforms. Has upstream been informed of this yet? -- Vincent Danen / Red Hat Security Response Team
