ntopng-enterprise starts consuming memory and dies

[simdim]

Hi all,
I am running ntopng Community v.6.1.231220 (FreeBSD 13.1) and seeing the following behavior:
ntopng starts, runs for a while but all of a sudden starts consuming memory until it quietly dies.

There is nothing substantial in the log:
