①cpu占用超90%

11-11 09:57:46.323 1565 2636 I am_meminfo: [396775424,208973824,1354592256,810651648,910783488]
②内存剩余200M，总的8G，内存占用极高

③检查anr的trace文件，没有死锁等异常，单纯是因为设备负载拉满了(①②点)，处理内容缓慢，导致超时发生大量anr

④在不安装额外应用的设备中跑moneky，基本不会有anr发生

⑤hht_ota_mgr经常占用较高cpu使用率
-----------------------------

原因为上述分析的⑤点，根本原因可以归结为，monkey测试时，启动了太多的应用与后台任务，造成cpu和内存拉满，导致设备响应慢
对于这个问题的处理方式
1.待后台任务数量控制功能开发完成，应该会有改善
2.hht_ota_mgr待客户分析
3.持续的系统优化需求开发...
