Needless to say Apple > documentation is useless. Maybe there is a way to reproduce the Lightroom's file access pattern from a shell script in a way that reproduces the problem. Then the same access pattern could be done from a FreeBSD client to see whether it happens there as well. Apple's SMB client appears to be FreeBSD's smbfs, however extended by Apple to support protocol version 3. https://opensource.apple.com/source/smb/smb-759.40.1/kernel/smbfs/smbfs.h.auto.html (Off-topic: I wonder if anyone has looked at porting this back to FreeBSD?) Maybe the differences are too great for the bug to appear on both systems.
