- Minor
I have started getting delays with Unraid file shares when doing any operation (viewing files in directoires, file copies etc) with Windows, this did work fine but has started happening over the last several weeks. I am also seeing associated errors in the UNRAID logs.
For example, from my windows PC if I open a new directory in Windows File Explorer, then File Explorer freezes for several minutes, then I see a warning in the UNRAID logs and then immediately Windows File Explorer comes back to life and shows the directory contents.
The log errors are all of the form (when viewing a share) :
May 6 12:53:55 UNRAID smbd[31869]: [2023/05/06 12:53:55.447545, 0] ../../source3/smbd/files.c:1199(synthetic_pathref)

or (when copying up an iso)

If I reboot the UNRAID server then it starts working fine for a few hours and then the freezes and log errors start up again.
Restarting samba with /etc/rc.d/rc.samba restart shows the following error in the logs
