Python Problem Solving: IOError: [Errno] Broken pipe

Error One:

Encounter a very strange problem, web.py code inside the error

IOError: [Errno] Broken pipe

Start command:

Nohup python xxx.py >> Xxx.log &

SSH log on to the machine, boot, does not appear

IOError problem occurs when remote SSH executes the startup script

View the process PID, LL/PROC/<PID>/FD found that stderr is the FD 2 file, unexpectedly is a pipe, is a broken pipe, the wrong place to find

Guess is SSH login in the past, Nohup will redirect stderr, default redirect to stdout, but SSH session stdout should be pipe, because the output from the remote machine to upload to the machine

Nohup redirect stderr to this pipe, when the SSH session ends, the pipe will naturally be closed, so when the program code in the stderr inside write things, will be error

Error Two:

In response to the above problems single-machine execution time, found no longer error, but in order to deal with the previous use of Nginx as a reverse proxy, the results appear

IOError: [Errno] Broken pipe

By F12 discovery, post loads a JS file timeout and appears 504 time-out

Check JS file no problem,

Recall, before the use of nginx before, this problem has been resolved, why suddenly appeared,

After data query, using the above nginx configuration to solve

The read time setting should be too short to cause a timeout:

Location/{Proxy_read_timeout 300; ......            .....           }

This kind of problem makes a person egg ache.
