What you expected to happen

I thought was the route between Oap Service and agent caused the problem first ,but i have already test the route between them and have no other problem .
And now I thought it might be the oap or agent file I didn't modify completely(because my environment is single node not cluster.i would checking them again)

How to reproduce

mateinfo-admin.sh restart i restart the service which would monitor by skywalking

Anything else

This seems the network is disconnected somehow. It doesn't mean your agent can't access OAP as always, but at least at this memont, gRPC network is not available.

I have tried again and now the phenomenon below the skywalking-api.log images shows that still throw error which yesterday i have propsed . the images also show that agent plugins have being loaded (the error was thrown before the plugins loading,i am not sure,but i think the error just affect few seconds,it won't interrupt the agent process ??)

after loading mutiple seconds ,it killed byitself without any error info

And I also went to see the skywalking webservice, it still shows no any service data but I found that the events interface , shows my service event .the event shows my service killed in multiple times

could you please have a watch again ? i can't deal with it

It can't kill itself, your health probe or k8s killed it.
Again, this is some mechanism only at your env. We don't have much to share.
And you can't have shutdown event from event, if it is a forcedly kill. Only graceful shutdown could report that.
As you mentioned it is killed, then yout error is expected anyway.
