The apiserver memory usage is high. The pprof command output shows that the processEvent method occupies a large amount of memory.The processEvent method takes up about 40% of the memory

### What did you expect to happen?

The APIServer memory usage is not high when the number of requests is stable.

### How can we reproduce it (as minimally and precisely as possible)?

I don't know how it happened.
