Yes , It was blocked when do cache operation in discovery event listeners when node left events arrival concurrently. I just do cache operation in another thread. Then the listener will not be blocked. The original cause may be that discovery event processor hold the server latch.when do cache operation in the listener,the server latch will be blocked(why,I am not sure).
