Proxmox VE 6.4 kernel panic during backup to NFS/CIFS

cn flag

For a few weeks, we experience systematic kernel crashes during the backup of two distinct Proxmox VE fully-updated 6.4 hosts running on 5.4.114-1-pve Linux kernel. Backups are using the stop mode and a NFS or CIFS mount.

I've taken the two enclosed screenshots of the hosts console after two crashes. They seem to both exhibit the same fib_get_table kernel method. What can I do to further diagnose the problem or avoid the crash ?

kernel panic 1

kernel panic 2

You can install and configure kdump to gather the kernel core after the crash has occurred, then analyze it with crash. See this Linux Journal article for more details.

In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
