When this issue arises, the PCCD CPU usage increases to 100% and stays at that level until the PCCD daemon is restarted.
Once PCCD enters this state, it is unable to process or compile any new configurations until the daemon is restarted.
The issue arises when NAT configurations are deleted and reapplied in a specific order. However, not all delete and reapply operations cause the problem.
Restart the PCCD daemon to recover from the issue.
Implemented logic to ignore stale data from previous operations during NAT rule compilation, allowing the current compilation process to continue without entering a loop.
