Actually no, as I don't have *one* smb.conf.
I'll add three of them (the last three were I had this problem) at the
end of this email.
As you can see they are not exactly identical.

I'd say not, but see the smb.confs.

One thing makes me wonder: at least in some setups, I have store "dos
attributes=no"; still I get them.

Not following you here... too much ignorance on my part :(

I'll try next time it happens (if it happens, as it did only once).
How do I know which process I shoudl attach to, however?

On my way to rebuilding Samba with debug info.
Thanks for the suggestion.
bye & Thanks
