[Samba] samba4.0.16 smbd internal error

[Sascha Willuweit]

Dear list,

I keep getting strange "internal error"s from smbd. I increased the log level to 3 and pasted the relevant log snippet. Does anyone know (or guess) what's going on? What should I check? Any direction to investigate?

Thanks a lot,
Sascha
