   ### Question
   - What do you want to know?
   skywalking后台CPU%，部署的单机，存储使用ES，也是单机。ES的CPU、内存以及状态都正常。
   本来想执行jstack查看skywalking进程的线程状态，但是执行后报错：
   `[root@iZbp1d40aso0xvdm5qgsawZ ~]# jstack 12145 | more
   12145: Unable to open socket file: target process not responding or HotSpot VM not loaded
   The -F option can be used when the target process is not responding`
   skywalking后台的日志一直打印：
   `2019-07-29 12:50:02,964 - org.elasticsearch.client.RestClient - 65 [I/O dispatcher 1] WARN  [] - request [POST http://172.16.4.52:9200/register_lock/type/16/_update?refresh=true&version=16117&timeout=1m] returned 1 warnings: [299 Elasticsearch-6.7.2-56c6e48 "Usage of internal versioning for optimistic concurrency control is deprecated and will be removed. Please use the `if_seq_no` and `if_primary_term` parameters instead. (request for index [register_lock], type [type], id [16])"]
   `
   运行环境：
   jdk版本：1.8.0_211-b12
   Skywalking版本：6.2.0
