First of all , thank you very much for your reply . and I still have a question .

you said it is unrelated to this message , but I still confused what cause such “action block” information ? can you give me some examples.
Best Regards

There is nothing abnormal in this log message. Seems you have configured
"init_limit_half_open = 1000". But as more than 2000 IKE_SAs are in
half-open state, the daemon is considered overloaded and rejects new
connection attempts.

No, it is unrelated to this message.

During shutdown, charon sends a delete for any active IKE_SA. If you
have many IKE_SAs active, not all delete messages might make it to your
peer, leaving some of them established. If the daemon shuts down
properly, it should clean up all locally installed SAD/SPD entries,
though.
