Had several crashes/reboots

Hi
I don't see any crash reports posted from the IP addresses listed as the source of your forum posts. We can look up the crash reports fine, but we need to know where they came from (IP address, IPv6 or IPv4) and approximate time.
If you get a crash report, you can copy/paste what you see of it in the GUI into a .txt file and attach it to a forum post as well.
Without having any detail whatsoever about what the crashes are, I can't offer any possible explanations. We certainly are not seeing that kind of instability here in our internal testing.
If the IP address didn't start with 212 for me please try the one logged on this post. (Quite often I'm on a VPN so may have posted when connected.)

Same address both times, no crash reports from it or anywhere close. IPv6 maybe? If you have it, the firewall prefers to use it.

Thanks for trying. My internet for my clients is routed through one of 3 VPN servers out of a pool of several dozen servers. Unless I have pfsense logging I can look into to see which IP address my VPN clients had at the time that the report was uploaded … you see the problem :).
Unless, it was sent over my WAN. In that case, since the IP doesn't change it would be easy. Can I send you a PM with the IP address?
Next time I'll make a copy of the crashdump and logs before uploading.
Maybe I should make a firewall rule that pfsense own traffic to your servers should always use direct WAN connection and not use the VPN connections?

Seeing the debate here - guys, since you've already flooded with dashboard with a bunch of UUID/Netgate Device ID nonsense, why don't you actually make use of it? Would be a whole lot easier to look up the crash report compared to digging for IPs.
Have I missed something here?

We could use the unique ID, but the crash reporting is meant to be simple/minimal. The IP and time are used on the server side, and no other system info is collected except what FreeBSD puts in the crash dump. It's probably due for an overhaul but that's not going to help anyone right now.
If there is any question about the report, just copy/paste it out to a text file from the report screen. When submitted, it always follows the default route on the firewall using IPv6 if it's available, or IPv4 if it isn't. For the vast majority of users, it's not a problem.

Hi
I wasn't prompted to send any crash report so unless it happened automatically it might be something you haven't received then. I was using in memory RAM disk so perhaps that stops the crash dump surviving, so I've turned that off now. I've updated to the lasted build of 2.4 RC and will see how it goes.
Many thanks for trying to help.
Regards
Phil

Nothing is automatically submitted, and RAM disks wouldn't matter. The only thing that would make a difference is whether or not your installation has any swap space. Without swap space, it can't store a crash dump from the kernel to be picked up on the next boot.
If you don't have any swap space then you'd have to hook up a serial console and let it run with a large buffer or logging to file and hope it catches the crash data as it happens.

Hi
Just seen a prompt to send the crash report to you, now done from this IP address. Hope it is helpful.

I see that one.

At the moment 2.4.1 is nearly identical to 2.4 except it has a FreeBSD 11.1 base.

Hi
Many thanks for the info and checking the crash report. I will try with a jump up to 2.4.1. I believe 2.4.1 will be close behind the official 2.4 release anyway. The crash for me happened after around 3 days of up time, it is the only crash I've had so far, so it is infrequent in my case.
Regards
Phil

i downloaded the 2.4 on the 20th (19th 23:00 release) and i had it running for about 3 hours before it too did a dump and rebooted. how ever i didnt think to grab the files. i was using mestick install and the device it was on is Qbox nT-A3350 9 if it helps…
