The earliest recollection of this bug is traced back to PAN-OS 11.1.10-h21 - September 09, 2026. This bug is fixed in PAN-OS versions 11.2.11, 12.1.5, 11.1.13-h2, 11.1.4-h32, 11.1.10-h21, 11.2.7-h11, 11.2.10-h4, 11.1.6-h29. Fixed an issue where the Elasticsearch Close Indices process closed more indices than expected and dropped the number of open shards below the minimum of 800 per Elasticsearch instance. This occurred because the process did not correctly account for the number of Elasticsearch instances when calculating the maximum number of allowed open shards.
