[Bug]: wait-active queue size does not match the actual number of goroutines

[aylei]

Is there an existing issue for the same bug?

• I have checked the existing issues.

Actual Behavior

CN has over 100K wait active queue size.

But there are only 200 goroutines waiting in waitActive stack:

profile: gorutines.txt

Also, there is no explicit goroutine hold txn handler in the goroutine list.

Expected Behavior

Wait active queue size should be correct.

Steps to Reproduce

从goroutine文件看，(*MOServer).handleConn( 的个数 与 (*waiter).wait(的个数相同。大概100个。
初步看不是fe的线程导致的active queue size异常。
