      Description

      Hello, I am seeing this error in the console messages each night during high activity of data transfer, when it happens it loses connection to the share and then reconnects, these are Windows Server 2019 machines connecting to TrueNAS. In the smbd.log file I see the following:

        dumping core in /var/db/system/cores

      Is there a way to provide the core dump file that is not public? Also is there anything else that would help?

      Thanks.
