Kernel panic - fatal exception in interrupt

[cYnd]

So I am running UnRaid 6.9.1 on a Intel Core i3-10100 mounted on a ASUS TUF GAMING B460M-PLUS with 16GB of Kingston HyperX DDR4-2666.

Everything was running smooth when I suddently noticed that occasionally my UnRaid server crashes with a Kernel panic - fatal exception in interrupt. Unfortunalety I can't attach anything else than picture, otherwise I would have provided the SysLog and diagnostics.

 

I also ran MEMTEST and it passed, so it shouldn't be the RAM.

 

 

Have you any ideas how to solve this?

Enable this then post that syslog after a crash, also post the complete diagnostics.

[cYnd]

I already enabled the SysLog, so I can provide it since the last crash. Please also find the diagnostics attached.

 

Do you see any abnormality in this?

I'm in the same boat. Been getting a kernel panic at least once a day. Memtest clean, syslog shows nothing. I've tried every trick I've found in this forum and others... I have no idea what to do next except downgrade.

Macvlan call traces are usually the result of having dockers with a custom IP address, more info below.

Okay, I indeed use docker with static IP addresses. Moreover I also enabled the setting "Host access to custom networks" in the docker settings because I am running PiHole and Unbound on my UnRaid Server as two docker containers and I want that my UnRaid Server is also using pihole and unbound as DNS servers. When I switch the setting off, I can't access these containers from within unraid itself.

 

Since I am not an network specialist, I don't know any other workaround to use my local dns server within UnRaid. To solve the problem of the crashes I disabled the setting again and I will check if the crashes persist or if this solved my problem.

 

However do you know how I need to configure my UnRaid server so it can access the PiHole/Unbound docker containers with custom IP addresses as a DNS server?

First link has alternative ways of configuring dockers.

Since I don't think that my network components support VLAN and I only got one NIC available there is no feasible solution.
