Public bug reported: Description: Ubuntu 14.04.3 LTS Release: 14.04
The Samba 'panic action' script, /usr/share/samba/panic-action, was called for PID 26738 (/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.
