Hello, To fix the mmap vulnerability I've upgraded one of my jail hosts from: "FreeBSD 9.1-STABLE #1: Sun Mar 17 08:48:35 UTC 2013" to: "FreeBSD 9.1-STABLE #3: Tue Jun 18 12:49:39 UTC 2013" One of the jails on this machine has a jailed zfs dataset: $ zfs get jailed gelipool/backups NAME PROPERTY VALUE SOURCE gelipool/backups jailed on local $ After the upgrade, when I start the jail, the machine panics. This is a remote zfs-only machine with swap on zfs, so far I have been unable to get a proper coredump. I have access to the console of the machine, and I have taken a couple of screenshots: http://imgur.com/2V0PBlf and http://imgur.com/OopP9Sp Any ideas what might have caused this ? It worked great before the upgrade to latest 9-STABLE. This is a production server, but I am willing to try any suggestions to get it working again. Thanks! Best regards, Thomas Steen Rasmussen ps. I have ordered a USB stick for the server which I will use to get a coredump, but I don't know when Hetzner will get around to it.
