elasticsearch长时间插入cup接近百分之百

心疼电脑，cpu百分之百运转...又卡
 默认配置下，短时间插入没问题。而一旦插入几个小时后，cup接近百分之百。
 
任务管理器查看是java.exx这个进程占据太多cpu。又通过pslist找到具体的线程。
 
通过线程得到日志。具体如下
 
"elasticsearch[Anti-Phoenix Force][transport_client_worker][T#2]{New I/O worker #2}" #18 daemon prio=5 os_prio=0 tid=0x0000000058a58800 nid=0x600 runnable [0x000000005be5e000]
