Description

Issue:
100% SWAP usage on pfSense+ 23.05.1-RELEASE after a number of days of uptime when the package NtopNG 0.8.13_10 is running on the system.

Troubleshooting Done:
Found on the UI of pfSense+ that the SWAP usage was at 100% after a number of days being up. Checking with top -w and running the command "o" checking SWAP usage I can see that ntopng is causing the swap to be high - I disabled the package and swap went down to 8% - This looks to have confirmed an issue with the package on the latest public release of pfSense+

top usage:
[23.05.1-RELEASE][]/root: top -w
