Hotfix versions were inferred because the vendor did not list them explicitly: 10.1.9-h1, 10.1.9-h2 Known affected versions were inferred from fixed-version data and were not explicitly confirmed by the vendor: 10.2.3-h14

The earliest recollection of this bug is traced back to PAN-OS 10.1.9 - July 22, 2025. This bug is fixed in PAN-OS versions 10.2.4, 10.1.9-h3. ( PA-3200 Series firewalls only ) Fixed an issue where, after upgrading to or from PAN-OS 10.1.9 or PAN-OS 10.1.9-h1, offloaded application traffic sessions disconnected even when a session was active. This occurred due to the application default session timeout value being exceeded. Upon upgrade or downgrade to or from PAN-OS 10.1.9 or 10.1.9-h1, offloaded application traffic sessions may disconnect after a period of time even if a session is active. The disconnect occurs after the application's default session timeout value is exceeded. This behavior affects only PAN-OS 10.1.9 and 10.1.9-h1. If you are on PAN-OS 10.1.9 and 10.1.9-h1, please use the following workaround. If you have already upgraded or downgraded to another PAN-OS version, use the following workaround in that version. Workaround: Run the CLI command debug dataplane internal pdt fe100 csr wr_sem_ctrl_ctr_scan_dis value 0 to set the value to zero (0).
