samba - Apr 2019 - Windows / / Windows 10 randomly lost connection to Samba share

hello,

we have a samba AD DC and some samba fileservers.

Version: 4.5.16-Debian (van belle repo)
Debaian version: 9.8

Some clients windows 7 and windows 10 randomly lost connection to share.
Loglevel is set to 3.
But i can't find any relevant entries in the log.
How can i debug the connection lost?

Best regards;

Hai Basti,

Anything in the windows even logs? 
This might be related to smb1 and windows automaticly removing it.  

Or something else. 
Can you check with mtr from a windows pc to the server.
And same check from server to winpc so your sure its not a defective network
component.

And a side notice, i recommend you to upgrade to 4.8 or 4.9. 

Greetz, 

Louis

smbstatus say that all open connections are SMB2_10 and SMB3_11
the windows log say: german text and errorcode C0000006

The Problem is on more than one client. All clients are win10. I think
is is a Problem with 4.5.16-Debian and SMB3_11.

I will try to set client max protocol to SMB2_10

I will do it when buster is released.
