Random segfaults within VM but memory looks good ?


Apr 18, 2022
I'm getting about 1-2 random segfaults per week in all kind of processes.

It happens in different qemu VM's, hasn't been on the proxmox host itself or in LXC containers yet.

I did run Memtest multiple times now in total for over 24hours and had 0 errors.

It's also kinda weird since it's a system I build in December 2022 and the random segfaults started around April.

Anything similar known, could there be an issue with qemu ? I already disabled ballooning.

My last option is to RMA the RAM but I don't think it's a hardware issue.
do I understand correctly that the segfault happens for different processes that are running within the guest VMs? Please share the output of pveversion -v and qm config <ID> for (some of) the affected VMs. What kernels are the guests running?
