---------------------------------

Hi Sandy,
    Thank you for your attention.
    We collected the jstacks stutus spaced few minutes When that phenomenon happening. We
get lots of tmp file of the jstacks status,but the ResourceManager Event Processor still blocked.
And few hours later, it still blocked. Finally, we restart the resourcemanager.
