Known affected versions were inferred from fixed-version data and were not explicitly confirmed by the vendor: 9.1.13-h5, 10.1.5-h4, 10.2.0-h4

The earliest recollection of this bug is traced back to PAN-OS 10.1.6 - July 22, 2025. This bug is fixed in PAN-OS versions 9.1.14, 10.1.6, 10.2.1. Fixed an issue where the firewall sent fewer logs to the system log server than expected. With this fix, the firewall accommodates a larger send queue for syslog forwarding to TCP syslog receivers.
