what is the maximum value for ntopng --max-num-host and --max-num-flow options
Hi.

I am trying to increase the --max-num-host value.

Each time i increase it to 500,000 ntopng serbice restarts every 20 seconds.

If i take it down to 350,000 the ntopng service is stable.

Is there a limit to the value i can input to this switch?

If yes, what's the maximum value.

Increasing the --max-num-host has an impact on the RAM used. My guess is that if you bring it to 500k, all the RAM available is exhausted and the OS kills ntopng.
What's the amount of RAM available? What are the specs of the machine you are using?
