Panic or segfault in Samba

  • In the last couple of weeks, I've had this error a few times.


    The only way I can seem to fix it is by rebooting the machine.


    Not quite sure why it's happening or how to get it to stop.

    You need to post the error on here.

    Dell 3050 Micro, i5-6500T, 8GB Ram

    Plugins - compose, cputemp, omv-extras, sharerootfs.

    Drives - 512gb SSD Boot, 1tb nvme Data, 16TB (8tbx 2 merg) Media,

    Docker - dozzle, netdata, nginx-proxy-manager, plex, prowlarr, qbittorrentvpn, radarr, sonarr, watchtower.

  • This is all the email contains when I try to access the specific folder, it's the same share that has errored both times.


    Code
    The Samba 'panic action' script, /usr/share/samba/panic-action,
    was called for PID 2317465 ().
    
    This means there was a problem with the program, such as a segfault.
    
    However, the executable could not be found for process 2317465.
    It may have died unexpectedly, or you may not have permission to debug
    the process.
  • I am now getting this error when I try to transfer a file from a MAC to the the OMV share - The samba service goes into a loop and sends me constanly e-mail alerts with different PIDs:


    "The Samba 'panic action' script, /usr/share/samba/panic-action,

    was called for PID 6930 ().


    This means there was a problem with the program, such as a segfault.

    However, the executable could not be found for process 6930.

    It may have died unexpectedly, or you may not have permission to debug

    the process."


    Something is broke
