There is no solution to the bug, quiet heart step by step troubleshooting, one hours in the morning to find out the problem

Originally thought that the end, the result is still quickly found out the problem, finish the bug good sense of accomplishment, troubleshooting logic is very important ~ I still very sharp drop ~

So the upload of hundreds of G file is no problem,

Problem reason: The upload can not be at the same time to create a new server file directory, must be established first, or when the transfer of the creation of folders will involve IO operations,

There will be time to wait, then may cause the upload wait time timeout, so the solution is the file directory has been established, so as to solve the problem of upload failure,

This is still the wrong time to see the file failure, upload a little bit to repeat the upload, see the upload directory constantly new directory to find the reason ~
