For certain Proxmox VMs, the service Proxmox VE VM Backup Status might have incorrectly alerted about missing backups. This was caused by a limitation in the Proxmox agent regarding the processing of logs and tasks. Specifically, log files larger than 5,000 lines were truncated.
A possible indicator that monitored VMs are affected by this issue is the presence of files named erroneous-... in tmp/check_mk/special_agents/agent_proxmox_ve. Especially if these files end with messages such as "Log for VMID=... not finalized", at least some VMs are likely affected. To immediately benefit from this werk, users should delete the folder tmp/check_mk/special_agents/agent_proxmox_ve. Otherwise, it can take up the maximum log age for this werk come into effect after updating Checkmk (the maximum log age is configured in the Proxmox agent rule).
