Samba error msg: smbd[9692] after upgrade to 380.68_4 (RT-AC68U)

[rac_ja]

Hi all,
I noticed some wired error messages which never appeared before. It just started after upgrade to Merlin 380.68_4 firmware. Is it some kind of bug? Here's my log:

If there's anything more you need for further investigation (some data, details), please don't hesitate to ask. I'll be thankful

Regards.

My first guess would be that a) the disk is formatted as NTFS, b) the files/folders on that disk were created by a Windows PC, and c) there is no user name on the Asus/Samba screen that matches the Windows user account that created the file/folders.

a) Yes, the disk was formatted as NTFS. It was done two years ago. Since then nothing was changed. It is connected the same as it was connected before the upgrade to 380.64_4.
b) Correct again, but it was like that since the very beginning. Some new folders might appear recently, but if they did, they were created the same way as always.
c) This is Windows 10 which connects to the Samba server on RT-AC68U, so the Asus login credentials are being used in Windows 10. The log comes from Asus.

It might be useful just to run this command from the Windows command prompt and verify the Windows account name associated with the SID:

wmic useraccount get name,sid

When I asked whether the files were created by Windows I meant, were they created whilst the drive was plugged directly into the Windows PC?

Does it only happen when trying to access certain files?

Is your Windows PC running in a domain or a workgroup?

wmic useraccount get name,sid

Done, results:

Some of them - yes.

Does it only happen when trying to access certain files?

Not sure, I'll be monitoring it.

The error messages have not appear again. They were probably justifiable, but I still don't know the reason. That was probably some coincidence, that they appeared shortly after update. Thread can be closed I guess.

PS Thank you ColinTaylor for your assistance.
