> Hi,

> The symptoms resemble that of this bug:
> https://bugzilla.samba.org/show_bug.cgi?id=13009 but the protocol
> versions differ. Also we’re pretty much on vanilla 4.7.11 so we
> have commit 81f31fd509.
> We have packet captures of the three protocol versions mentioned

> Any idea what might be the issue?
