Message:
[lo] Flow Export Queue Len [0 tot queued][0/0 IPv4/v6][Drops queue too long 0/0 IPv4/v6][0 tot exported flows]

Datasheet:
OS: Ubuntu 18.04.2 x64
switch into ntopng.conf:

--daemon
--community
--dns-mode 1

Note:
a. It does not matter if the interfaces are declared with the switch --i
b. It does not matter if IPv6 is disabled or not

Description:
In the image below the problem is reproduced in each step:

  1. The message comes out every second, without having accessed NtopNG
  2. When entering NtopNG through the browser (mozilla, chrome, etc., with the user and password credentials), the following message appears: 08:10:29 WARNING: Demo mode expired
  3. Then, it appears the message Terminated flow exporter for lo and the message [lo] Flow Export Queue Len [0 tot queued][0/0 IPv4/v6][Drops queue too long 0/0 IPv4/v6][0 tot exported flows] is repeated once more and it does not come back

This is cento that stops exporting as it doesn't have a valid license. So it's normal.
