The driver was unable to create a connection due to an inability to establish the client portion of a socket.This is usually caused by a limit on the number of sockets imposed by the operating system. This limit is usually configurable. For Unix-based platforms, see the manual page for the 'ulimit' command. Kernel or system reconfiguration may also be required.For Windows-based platforms, see Microsoft Knowledge Base Article 196271 (Q196271).

是linux环境还是windows环境呢？有可能是资源申请不到。在linux下有一个最大打开文件的限制，此限制同样适用于socket的申请，因为linux下将所有设备视作文件。可以使用ulimit进行更改。
