pfSense has detected a crash report or programming bug

Hi, can anyone help me to understand what is this and how to solve it? We just saw this notification after we try to open the firewall thru gui because our network is very slow. The dashboard itself loads almost forever. Thank you so much.

Crash report begins.  Anonymous machine information:

You have the disks widget on the dashboard I assume?

Does it show the correct information?

What filesystem/mount points do you have?

ejmalibong

@stephenw10 Hi sorry for late reply, I'm sick. Anyway, do you mean this one?

I think it shows the correct but it loads responds very very slow and we experience occurence of disconnected network for like 10 minutes then it reconnect again.

ejmalibong

@stephenw10 I shows an error from the dashboard that's why we think that is the problem but we do not know exaclty what it is and how to solve it except to reinstall the pfsense and back the configuration from scratch.

stephenw10

Try expanding the mount points in the disks widget. Any errors shown?

Try removing the disks widget. Does that stop the slow page loads?

ejmalibong

@stephenw10 Expanding the mount points in the disk widget? Did you mean this?

I tried to remove the disks widget and response unlike before but still slow. But anyway, it is not the thing that we worry about. It is the re-occurence of network disconnection and slow local network. Some PC show "No internet access" like they have a globe icon from network (Windows PC) but they have internet and local network, its just very slow. So much difference from before since this errors pops out.

stephenw10

Any errors in the system logs when this happens?

Or anything logged at all? Perhaps there is an interface relinking causing packages to reload.

ejmalibong

@stephenw10 I will get the system logs. We just noticed this problem when the whole company have no network connection. I mean there are PC that shows "No internet access" but they have actually, it is just very very slow even file server takes a lot of time to load from each PC. When we check the firewall, it already have this error, so we restore the last backup but still not working. During that time, the dashboard also shows "Unable to check updates". When we try to remove or reinstall some packages, it shows "Another instance of pfSense-upgrade is running."

ejmalibong

@stephenw10 It is the system logs.

stephenw10

That sounds more like an actual upstream connectivity issue. Perhaps the ISP is passing you an IPv6 address and isn't routing it correctly. That can present as delays when clients have to try IPv6 and wait for it to timeout before trying IPv4.

ejmalibong

@stephenw10 Do you mean they do changes on our configuration? Something like that? Because we already conduct internet speed test and seems no problem with their end. Does it mean this error the system is showing has no bearing from what we are experiencing right now?

stephenw10

Which interface is re2? Are those MAC addresses known devices?

Try running at the command line (not in the gui): pkg-static -d update

Does it fail to connect to the pkg servers? How does it fail?

@stephenw10 said in pfSense has detected a crash report or programming bug:

Actually, it has no MAC address declared. It should be the MAC address of the firewall itself or the MAC address of the router or hardware provided by our ISP?

Try running at the command line (not in the gui): pkg-static -d update

I'm sorry, cannot provide you answer right now because I'm just remoting. I will try tomorrow in the firewall itself.

stephenw10

Those MACs are from LAN side clients that appear to be moving. You might have some IP conflicts there if any of those hosts are using static IPs.

You can connect to the firewall using SSH remotely if you want to test that.

You mean there are devices that uses the same IP? Basically, we encoded to DHCP Leaeses or Server each devices that is handled by IT like this:

Or you mean there a device that uses the same IP used by re2 which is 192.168.20.254?

You can connect to the firewall using SSH remotely if you want to test that.

I will research about SSH, this will be so helpful for us.

stephenw10

I mean more than one device no the LAN trying to use, for example, 192.168.20.130.

There are some legitimate reasons why you might see that. But if none apply to you then you might have a real conflict in which case I'd expect to see some problems connecting from those devices.

@stephenw10 We will try to find out. Thank you very much for your effort.
