post 请求时有时会长时间阻塞

[Michael_g]

post 请求时有时会长时间阻塞，长达10多分钟，继续执行后有时会成功有时失败，这是为什么？我设定了socket 超时为60秒，为什么还会阻塞这么长时间？下面是调用堆栈，程序阻塞在了 OSNetworkSystem.writeSocketImpl 这个方法，这是个本机方法不能跟踪了。我用的是android 2.1。

确实是会阻塞的，因为网络的关系，建议你开个thread跑，就成了

[Michael_g]

阻塞是肯定的，但为什么会这么长时间？有谁遇到过这个问题？

[life02]

我就遇到过啊，那是因为你的网络不稳定啊，连接不上哈

[南瓜饼]

很可能是网络不行 最后公司升级服务器和带宽就没这问题了

[Michael_g]

我是在局域网测试的，网络不稳定基本可以排除。
