FastDFS多線程并發(fā)寫入文件拋異常

jiaomicha

參照魚大的例子寫的多線程并發(fā)寫入文件，有10個(gè)線程，1個(gè)tracker1個(gè)group3個(gè)storage，大概每寫入1800個(gè)左右的文件時(shí)候就會(huì)拋出異常如下：
java.net.SocketException: No buffer space available (maximum connections reached?): connect

看異常好像是說超出了最大連接數(shù)，buffer空間不足，但是我調(diào)大了storage配置文件中的max_connections后還是一樣的情況啊。

想請(qǐng)教多線程寫入的時(shí)候配置文件需要怎么修改？多線程寫入的API調(diào)用有什么講究？謝謝
