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 <tt>erroneous-...</tt> in <tt>tmp/check_mk/special_agents/agent_proxmox_ve</tt>. 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 <tt>tmp/check_mk/special_agents/agent_proxmox_ve</tt>. 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).
