Ntop-NG high CPU utilisation after enabling IPv6

[Tamas Halmai]

I have recently enabled IPv6 on my WAN interface + 3 * Intranet IFs and noticed that CPU utilisation increased from the 5% baseline to ~50% (which obviously increased CPU temperature to ~80 celsius from ~50 celsius). The high CPU was caused by Ntop-NG. After disabling Ntop-NG everything is back to normal (including dual-stack).

The versions I run:
- OPNsense: 25.7.9
- Ntop-NG:  1.3

Please advise what parameters to tune to be able to re-enable Ntop-NG?

Thanks in advance,
