version 3.9.190208 does not crash, what ever is causing the crash was introduced between 3.9.190208 and 3.9.190314

[LunkwillAndFook]

I am experiencing the same issue. I will try downgrading to 3.9.190208 to confirm whether that works.

[Tijah82]

I have the same problem with the version ntopng_3.9.190314-6347_armhf.deb. I have reinstalled the previous version and it works very well.

[emanuele-f]

Fixed in ntop/nDPI@6c9fbc2 . A new package will be available in two hours.
