samba - Jan 2020 - delayed write files errors

Hello Rowloand,

ok, I just keep "default" for the mounting.

I changed the path of my share :

[homes]
comment = User Home Folder
path = /home/%U
read only = no
follow symlinks = yes
wide links = yes
browseable = no
hide files = /desktop.ini/$RECYCLE.BIN/

I need Wide Links because in the share there are symbolics links to 
outside the share.

Anyway, I still get the same error with all this files :

 ??? mrxsmb :
\.system\Thunderbird\profile.default-release\calendar-data\cache.sqlite-shm
\.system\Thunderbird\profile.default-release\cookies.sqlite-shm
\.system\Thunderbird\profile.default-release\places.sqlite-shm
\.system\Thunderbird\profile.default-release\favicons.sqlite-shm
\.system\Thunderbird\profile.default-release\webappsstore.sqlite-shm

There is new errors in the samba log, like kerberos errors. I don't know 
if this errors are normals.
Also, I can see the file favicons.sqlite-shm?in the samba log (@ 
[2020/01/04 23:59:55.709000,? 2]) with som errors.

Any idea ?

You were using a share called '[users]' where a 'path' parameter
is
required, but you have now changed it to '[homes]'. This is a special 
share and does not allow the use of the 'path'
parameter.

OK, but just ensure they cannot link to somewhere they shouldn't (such

If there is nothing in the Samba log, then it either isn't a Samba 
problem, or it isn't appearing because the log level in smb.conf is too low.

What is the full log fragment ? The lines around the error.

Hello you all,
we had similiar problem with Thudnerbird and Firefox running from
redirected folders. We did not find a fix for it. We just did not
redirect the profile folder anymore.

I posted about this last year:

However, the use of [homes] works correctly. But ok, I changed the name 
of the share as you advise me.

Yes it's a Windows Event, mrxsmb, ID 139. Strangely it's always for 
*sqlite-shm files.
