I think you are on to the right thing about the echo and DHCP, except
they are in other order.
What we do know is that the linux cifs client, and other clients no
doubt, send an echo if they feel the server is un-responsive.
Is the DHCP renewal at the normal point (compare with previous
renewal), or could this be both related to an underlying issue: lack of
two-way link at the network layer? Could Samba be listening only, but
the client not getting the responses due to dodgy networking, and then
it finally breaking down causing NetworkManager to re-try the whole
Can you rule out a dodgy network switch?
