定位这个Bug的那么久，到这里我可以说下这个Bug产生的问题流程：

1.当我们不断的请求一个接口，我这里大概是1s三次左右
2.某一次出现了这个错误HTTP FAILED: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.，在qa002环境
3.就会导致出现OkHttp出现警告，DiskLruCache /data/data/com.xfxb.paperless.prd.debug/cache/cache is corrupt: /data/data/com.xfxb.paperless.prd.debug/cache/cache/journal: open failed: EMFILE (Too many open files), removing ，这个警告的意思就是说正在删除缓存问题，正在移除中
4.往下进行就会报错没有找到文件，这是HTTP缓存机制，缓存对于移动端是非常重要的存在。减少请求次数，减小服务器压力.本地数据读取速度更快，让页面不会空白几百毫秒。在无网络的情况下提供数据。
5.然后这就会参数异常 java.net.SocketException: socket failed: EMFILE (Too many open files),这个异常会抛出来，但是不会影响到程序的崩溃
6.然后使用者不知道，又去点击下一次的网络请求，也会同样走上面的流程
7.在安卓上就会ANR，程序就会崩溃
8,解决办法，
- 一：我在优化网络请求，
- 二：如何避免请求抛出错误HTTP FAILED: javax.net.ssl.SSLHandshakeException:
