@Andrew,
Samba master - what do you mean? A clean compile and install from genuine
samba.org sources? As a matter of fact, I was thinking about it....
Let me do the tests now, with tcpdump. Will send some logs and outputs
later on.
You've asked previously - this is the smbstatus, already on the latest
kernel/samba versions.
The problem is persistent, no wonder...
