The earliest recollection of this bug is traced back to PAN-OS 10.1.1 - July 22, 2025. This bug is fixed in PAN-OS versions 11.0.5, 10.2.7. ( M-600 Appliances in Log Collector mode only ) Fixed an issue where Panorama continuously rebooted and became unresponsive, which consumed excessive logging disk space and prevented new log ingestion. The ElasticSearch process on the M-600 appliance in Log Collector mode may enter a continuous reboot cycle. This results in the M-600 appliance becoming unresponsive, consuming logging disk space, and preventing new log ingestion.
