Installed packages

@Gokulapandi

pretty sure this is the upgrade problem and I recommend the update over ssh!

Maybe ntopng is the CPU load issue, try to disable/remove it.

@slu

Ntopng service has already stopped. I will install the 2.7.2. over ssh
how do we find the CPU usage issue and network connectivity issues ?

No idea, sorry. This must depend on your setup.

[Gokulapandi]

@slu

Thanks.

Before upgrading the version. It was working fine, there was no CPU usage and network connectivity issue s mentioned earlier.

@Gokulapandi

There is something else, did you mention somewhere you use a VM ?
If so :
The pfSense from last decade, 2.4.5, used an very ancient FreeBSD kernel.
The recent 2.7.2 uses what, freeBSD 14 or even 15 ?
The hypervisor model or VM settings should be 'updated' (upgraded ?) also.
if not, bad, or even horrible network virtualization has been seen before.

@Gertjan

Thanks for your response.

Firewall current kernel version is FreeBSD 14.0-CURRENT amd64. We are running pf sense in physical machine.

our issue is below - FYI.
only If a few users using connecting in the firewall, it's working fine. When connecting more users in firewall, only we can able to use the internet, cant access another network (ipsec network/ openvpn network). After rebooting the firewall, everything is working fine

[stephenw10]

Does it happen immediately or after the firewall has been running for a while? Does the interrupt load increase slowly?

What NICs do you have in that box? I can see re0 there.

Ok, good to know.

I didn't understand why this installed :

When connecting more users in firewall,

How many users? Are you using the Captive Portal?

[Gokulapandi]

@stephenw10

We are not using captive portal. Around 50 devices are connecting in LAN.

Interrupt load increases as number devices connection increase in LAN.

"LAN in" Traffic has reaching till 300 M as cpu interrupt load increases.Then we need to reboot firewall.

Is it all Realtek NICs?

[Gokulapandi]

@stephenw10

We are using three NIC.

We are using two WANs and one LAN.

WAN1 is Intel adapters
LAN is Intel adapters
WAN 2 is Realtek adapter

[stephenw10]

Are you load-balancing traffic between those WANs?

[Gokulapandi]

@stephenw10

No, We are not doing a load balancer as secondary WAN has less bandwidth.

FYI - We have updated now the version to 2.7.2

[stephenw10]

What does vmstat -i show is creating the interrupt load?

[Gokulapandi]

@stephenw10

This is taken before issue.

[stephenw10]

Ok nothing too huge there. What does it show when the issue happens?
