System crashing

[agogiu]

Hello all,

I've been using OPNsense for about one month. It is a home setup with two main clients and a few other devices around the house. I have these weird system crashes whenever I:
- download torrents
- have MS Teams calls
- syncing a lot of OneDrive files
- and weirdly enough, when I do internet speed tests.

I also had ZenArmor firewall enabled and disabling it reduced the frequency of these crashes. However it still happens and when it does all my clients are cut off from the network and I have to reboot the machine that runs OPNSense.

I run it on a mini PC with 4 core 2Ghz Celeron CPU and 8Gbs of RAM. It usually never goes above 20% CPU and around 45% RAM. I don't know what happens during the crash. I searched whatever logs I could found nothing relevant.

I don't want to quit using OPNsense so any suggestion would be appreciated.

Thank you!

Hello,

( I have already opened a thread in the German subgroup about this )

I have experienced similar problems this weekend.

In two days, my OPNSense shut down three times and could only be revived via reboot.

At one time I was doing large downloads and the internet line was also fully loaded for a long time but at the other two times there was no particularly high internet traffic active.
Only a reboot fixed the problem.

The WebGUI was still accessible within the same VLAN, ssh access was no problem. I restarted some services as a test but without success.
I did not find any messages in the log files that indicate problems.

Also the SNMP and NetDate graphs showed no problems.

Hardware:
Fanless Mini-PC with Core-i5, 32GB Ram, 250GB SSD
But it is forced cooled by a fan.

ZenArmor is not installed on me, the installation caused a constant restart loop and was not usable.

Cause of the failures:  I have no idea at the moment

for both systems what are the network cards you're using - crashes under high traffic load can often be down to nic hardware/drivers

In my server 8 x i211AT Intel network cards are installed ( onboard )

The outages in my case were only at one point in time when the internet line was very busy with almost 950 MBit/s, at the other two points in time it was not even 20 Mbit/s.

In addition, the system has been running smoothly for several months and I had not made any changes in the last 2 weeks.

I have a post on the 22.1 Prod board. I haven't gotten any replies.


"Hello group. I am a new user and looking for some assistance on t-shooting an issue. I installed OPNSense via USB boot. the install went as expected. No issues. I have it currently segregated in a lab environment (no WAN connection to internet). It is serving DHCP to 3 separate VLANs which are trunked to my Cisco 3850 switch. I can receive DHCP from all 3 vlans. However at some point over the night the server becomes unresponsive and I am unable to ping its gateway interface, or access the web frontend. I have logging enabled to "debug".  Looking at the log these are the last entries from the night before and the entry after my reboot.

Are there any files/logs/ console output I could provide to help determine why the server suddenly stops responding?"

Im thinking it might be a issue on the motherboard (some sort of BIOS setting ).
