Hi @ningmingxiao. Thanks for your PR.

I'm waiting for a containerd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

how it happened?
when restart containerd
A:
func (c *criService) recover(ctx context.Context) ->loadContainer->startContainerExitMonitor

startContainerExitMonitor
go func (){
c.containerStore.Get(e.id)
}

B:
func (c *criService) recover(ctx context.Context) -> containerStore.Add

if A (c.containerStore.Get) is running before B, if container event is coming,events will be droped

#11579 will fix close it.
