Things I checked so far:
- Using different filesystem on server does not fix the problem.- Updating client to cifs from debian testing or unstable does not fix the problem. - Updating the linux kernel on the client to 3.14 from backports does not fix the problem.
- The error always occurs only once. Just executing the same mount command again leads to a successful connection. Mounting other shares afterwards works on the first call.
- Network is complete dual stack (IPv4+IPv6). Disabling IPv6 on client does not fix the problem.
- Server has multiple IPv4 and IPv6 addresses on the primary interface. This may be problematic, I will investigate further.
- Using different usernames, with/without password, with "nounix", with sec=ntlm or sec=ntlmv2 does not fix the problem.
Maybe someone can shine some light on this... Regards, Thomas
