We are using TM ThriftServer. Sometimes, some IOThreads get stuck in libevent and keep consuming 100% CPU. I did some google search, it seems to be a libevent/epoll bug ( https://www.google.com/search?q=libevent+high+cpu+fbthrift&oq=libevent+high&aqs=chrome.0.69i59l2j69i57j0l2j69i60.4555j0j1&sourceid=chrome&ie=UTF-8#q=libevent+high+cpu ).

Has anyone seen the similar issue before?
