CPU spike to 100% from System usage [possible pvestatd bug]

[j1a2o]

Last night, my CPU spiked to 100% due to System usage. When looking at syslog around the time it happened, these are the relevant lines I see:

Jan 12 23:47:13 pve pvestatd[3817]: VM 102 qmp command failed - VM 102 qmp command 'query-proxmox-support' failed - got timeout

Jan 12 23:48:06 pve pvestatd[3817]: VM 102 qmp command failed - VM 102 qmp command 'query-proxmox-support' failed - got timeout

Jan 12 23:51:07 pve pvestatd[3817]: VM 102 qmp command failed - VM 102 qmp command 'query-proxmox-support' failed - got timeout

Each of these events correlates well with 1 of those spikes. This seems like it might be a Proxmox bug?

likely the other way round - load spike -> VM couldn't handle command in time -> timeout message logged
