Samba share stops working after some time

Hello All,

I have decided to migrate my fileserver from a physical FreeNas box to a virtual Xigmanas box with UFS filesystem to integrate it in my veeam backup.. The reason i chose for Xigmanas is because it's possible to use a non-zfs filesystem.
I'm still testing Xigmanas. At this moment the virtual machine is connected to the domain and has 1 file share. I use domain users/groups to set permissions on the file share.

For some reason the file share stops working after some time. When checking the logs in the webgui i can see the following lines repeating. I have replaced my domain name with domain.com

Code: Select all

Once this error occurs, i'm unable to connect to the file share anymore. To fix the issue i have to reboot the machine.

What could be the issue?
