I have the same problem: The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 1293 (/usr/sbin/smbd).
This means there was a problem with the program, such as a segfault. Below is a backtrace for this process generated with gdb, which shows the state of the program at the time the error occurred. The Samba log files may contain additional information about the problem. If the problem persists, you are encouraged to first install the samba-dbg package, which contains the debugging symbols for the Samba binaries. Then submit the provided information as a bug report to Ubuntu by visiting this link: https://launchpad.net/ubuntu/+source/samba/+filebug [Thread debugging using libthread_db enabled] 0x00007fd406b8edee in waitpid () from /lib/libc.so.6 #0 0x00007fd406b8edee in waitpid () from /lib/libc.so.6 #1 0x00007fd406b26a79 in ??
