Hello everybody,
we have an annoying problem with our samba server randomly disconnecting the home shares.
Our "Application Data" folders as well as "Desktop" are redirected to directories in the user's home folder outside ".profiledata" to avoid the copying during logon /logoff.
>From time to time clients get an error message "Delayed Write Failed" claiming a write error regarding the thunderbird or firefox profile. At the same time all Desktop symbols are disappearing. The issue can be worked around by logging out and in again.
>From wireshark network captures we can see the server sending an STATUS_INVALID_HANDLE
is in response to a QUERY_FILE_INFO on the problem file.
The setup:
- OS Solaris11 / x86
- Samba 3.5.10
- some
The server was recently updated from OpenSolaris running Samba 3.4.x
any suggestions are really appreciated....
Thx
Carsten
