BTW,在传输一个(pcs upload)较大文件（几百兆+）时没有这种错误，而在批量传输(pcs synch)多个较小文件（几十兆+）时该错误经常会发生。
错误出现后速度会由原来的几兆~几百k下降为十几k。

PS: ...and this error (usually only once per file):
Upload slice failed, retry delay 10 second, tid: 0x7f7211fef700. message: Timeout was reached: http://c.pcs.baidu.com/rest/2.0/pcs/file?method=upload&type=tmpfile&app_id=...[ ok ]...file

@GangZhuo 今天发现一个可能是造成这个error的原因，文件名较长，而且包含空格。
但是，我是用的pcs synch命令，后来单独用pcs upload改了一个简单的名字就一次成功。
