Hello everyone, I hope you are very well and can help me, I happen to have a version of PVE 6.0-4 and recently I have experienced strange behavior on my VMs.
I noticed this in the backup task, because it began to throw an error "got timeout", this only happened with a couple of VMs, but over time the problem was replicated in more Vms, and were no longer only two, but began to be 3 and then 4. so it happened with many Vms randomly.
Investigating further I realized that these same VMs, gave an error when trying to enter the console option, displaying a message "Failed to connect to server", when viewing the log in the task option appears this
VM 104 qmp command 'change' failed - got timeout
TASK ERROR: Failed to run vncproxy.
While for the backup task it shows this
NFO: include disk 'virtio0' 'local-lvm:vm-203-disk-0' 500G
INFO: backup mode: snapshot
INFO: ionice priority: 7
INFO: creating archive '/mnt/pve/pbs01/dump/vzdump/vzdump-qemu-203-2022_12_04-17_33_46.vma.lzo'
ERROR: got timeout
INFO: aborting backup job
ERROR: VM 203 qmp command 'backup-cancel' failed - got timeout
ERROR: Backup of VM 203 failed - got timeout
It seems that both problems are related to each other, but I can't figure out why it happens and how to fix it. Previously a restart of the VM seemed to work but it is not an option at this time.
