Random crashes after reinstall 16.7

[Free_Norway]

Hi all

After the upgrade from 16.1 to 16.7  didnt work very well(openvpn clients didnt work, gateways shown up twice) i decided to reinstall 16.7 last weekend.
After fiddeling around for a while with the USB-pen installer issue i got it installed and after a komplete new configuration everything was working perfect.

Now on monday things got strange.
After running for some time, the opnsense box rebooted on it's own when i was at work.
After coming home i checked opnsense and during my checks i rebooted again 4 times in 20/25min.
Then i stresstested it with setting up a couple of downloads with about 65-75 Mbps troughput over VPN.the firewall ran without a hickup.
Today it started again with the random reboots.

Can anybody tell me where to find the complete log?
The logfile under System-»Log file only shows logs after the last reboot

Regards
Sebastian

Hi Sebastian,

Is this a nano install? Did you enable /var MFS in the misc. settings? I'm asking because normally you'd see a crash report that you can send to us that has the kernel crash... but...

If there are no kernel crashes the power is probably lost and the device boots up again, which would point to a failing power supply? How old is your hardware? Are there any power outages? Can you confirm that uptime is really resetting?


Cheers,

Hi Franco

Thank you for the reply.

It's an cdrom/VGA install on a 1,5 year old firewall motherboard.
The motherboard is mounted in an older server chassis with dual power supply and the whole System(firewall, switch, AP...) is on an 6KW Eaton UPS.
The same setup has run the week before the upgrade for 48 days without a hiccup, but I will try another power supply.
As I wrode in the firt post this happens most often when the system is "idle", could it be a power state or memory issue?

PS:The only difference from the previous install is that the SSD is now GPT not MBR.
