The earliest recollection of this bug is traced back to PAN-OS 11.1.10-h12 - September 04, 2026. This bug is fixed in PAN-OS versions 11.1.13-h1, 11.2.11, 11.1.14, 12.1.5, 11.1.6-h25, 11.1.10-h12. ( PA-5220 firewalls only ) Fixed an issue where the ikemgr process crashed intermittently, which caused IPSec tunnels to go down randomly. With this fix, the IKE Security association data structures are accessed in a thread-safe manner, and the ikemgr process does not reference an invalid memory pointer during teardown operations. ( PA-5220 firewalls only ) Fixed an issue where the ikemgr process stopped responding intermittently, which caused IPSec tunnels to go down randomly. With this fix, the IKE Security association data structures are accessed in a thread-safe manner, and the ikemgr process does not reference an invalid memory pointer during teardown operations. ( PA-5220 firewalls only ) Fixed an issue where the ikemgr process crashed intermittently, causing IPSec tunnels to go down randomly. The fix ensures that the IKE security association data structures are accessed in a thread-safe manner. This prevents the ikemgr process from referencing an invalid memory pointer during teardown operations and provides stability.
