Running samba4 recent GIT build from:

commit 51c612e4de9e52bf1967172728bb2dc7b63f9cd7

    Remove check_col from generated DCE/RPC dissectors.



Just had samba crash during the logon of a domain-joined Windows 8 client. Has been otherwise very stable for the last month or two.

I have other logs if they'd be helpful.

They all have a fair amount of:

[2013/10/10 03:29:33.645966,  2] ../source3/modules/vfs_acl_xattr.c:193(connect_acl_xattr)
  connect_acl_xattr: setting 'inherit acls = true' 'dos filemode = true' and 'force unknown acl user = true' for service IPC$

and 


[2013/10/10 03:29:44.334827,  2] ../source3/smbd/smb2_server.c:3250(smbd_smb2_request_incoming)
  smbd_smb2_request_incoming: client read error NT_STATUS_CONNECTION_RESET
Comment 3 Volker Lendecke 2013-10-11 07:03:17 UTC
Is this repeatable? If so, can you get us a debug level 10 log and a network trace of that connection? See

https://wiki.samba.org/index.php/Capture_Packets
and
https://wiki.samba.org/index.php/Client_specific_Log

for more info how to do this.

Thanks,

Volker
