Public bug reported:

Betriebssystem	‪Ubuntu 16.04.6 LTS‬
Produkt	Plesk Onyx 
Version 17.8.11 Update #53, zuletzt aktualisiert: 21. Mai 2019 05:47:33


The Samba 'panic action' script, /usr/share/samba/panic-action, was
called for PID 3090 (/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:
