Duplicati looks to not correctly close filehandles

Putting this here as I haven’t updated to .104 yet, but while diagnosing another Duplicati issue I noticed this on a Linux backup, which started at 0:00 and it’s currently 19:00 so 19hrs

The above is the open file list of the destination backup, a Windows Server 2025, using SMB and the 3rd of the backups that run sequentially and only backs up the databases failed with:

Why are these files still all open? Restarting Duplicati released all the files and I will see what happens tomorrow.

** Additional ***

Two of the three connections from Duplicati are not doing any backups, yet their connection is held open - fyi, the other two non-Duplicati are mount points, not dynamic connections like I assume Duplicati would make.
