FYI: I have reported this exact same backtrace (at least the last 3 calls) here https://bugs.launchpad.net/ubuntu/+source/samba/+bug/667269?comments=all
for us, winbind is dead, black screen on Console, no longer can ssh into machine using Active Directory credentials. I must kill any winbind processes running, then restart it. It's happening more frequently, (hourly) on 25% or more of our 80 64-bit LucidLinux machines, integrated with ActiveDirectory(winbind). I am desperate to get this bug fixed. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in Ubuntu. https://bugs.launchpad.net/bugs/753330 Title: The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 1783 (/usr/sbin/winbindd). -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
