HA failover triggerd due to "Out of memory condition detected, kill process".

• System logs shows OOM logs for multiple processes : "2025/04/03 07:55:49 critical general general 0 Out of memory condition detected, kill process 9809"
• Core files are generated related to all_task after the crash.
• Device has large sdwan configuration.
• Slow memory leak is observed for log-receiver process with subsequent commits.

• Palo Alto Networks Firewalls
• Supported PAN-OS
• SDWAN

SDWAN config reading in log-receiver causing leaks in the memory with subsequent commits.

Resolution:

1. The issue will be resolved under PAN-287314 in the upcoming versions.
2. Upgrade the PANOS to any of the fixed versions when released.
   • 11.2.8
   • 12.1.2
   • 12.2.0
   • 11.1.11
   • 10.2.17
   • 10.2.9-h24

Workaround:

1. Restart Log Receiver from CLI by running, "debug software restart process log-receiver"
2. Frequency of w/a execution depends directly of the amount of memory being leak and will vary on case by case.
