The Samba 'panic action' script, /usr/share/samba/panic-action,
was called for PID 26441 (/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
Debian.  For information about the procedure for submitting bug reports,
please see http://www.debian.org/Bugs/Reporting or the reportbug(1)
manual page.

To enable execution of this file add
	add-auto-load-safe-path /lib/x86_64-linux-gnu/libthread_db-1.0.so
	line to your configuration file "$HOME/.gdbinit".
	To completely disable this security protection add
		set auto-load safe-path /
		line to your configuration file "$HOME/.gdbinit".
		For more information about this security protection see the
		"Auto-loading safe path" section in the GDB manual.  E.g., run from the shell:
			info "(gdb)Auto-loading safe path"
			__strftime_internal (s=<optimized out>, maxsize=<error reading variable: Cannot access memory at address 0xffffffffffffff29>, format=<optimized out>, tp=<error reading variable: Cannot access memory at address 0xffffffffffffff11>, tzset_called=<error reading variable: Cannot access memory at address 0xfffffffffffffef1>, loc=<error reading variable: Cannot access memory at address 0xffffffffffffff09>) at strftime_l.c:1407
			#0  __strftime_internal (s=<optimized out>, maxsize=<error reading variable: Cannot access memory at address 0xffffffffffffff29>, format=<optimized out>, tp=<error reading variable: Cannot access memory at address 0xffffffffffffff11>, tzset_called=<error reading variable: Cannot access memory at address 0xfffffffffffffef1>, loc=<error reading variable: Cannot access memory at address 0xffffffffffffff09>) at strftime_l.c:1407
			Backtrace stopped: Cannot access memory at address 0x9
			A debugging session is active.

				Inferior 1 [process 26441] will be detached.

				Quit anyway? (y or n) [answered Y; input not from terminal]
