IOError: [Errno 32] Broken pipe</textarea>

i don’t get proper error message just show this error message everytime

if i restart server and follow same steps then showing proper message and after sometime same error message appear like above screen.

my server configuration
Dell R710 Model

It’s because of your internet connection was lost while bench start command or you didn’t resume your ssh session in terminal.

It’s ssh connection issue not with ERPNext

You can fix this issue using:

To Fix the current issue use:

sudo  ps -aux | grep bench command in your terminal and kill all the  listed process using process id

To kill the process use:

 sudo kill -9 <int-process-id>
9 parameter for forcing to kill the  process.



This process is for bench start when we lost ssh connection but not for broken pipe it is still showing same message when connection lost

Yeah, Pipe ssh lost cause the python pipe broken. It’s happened with me many times.
You need to restart the server or kill the bench process and try again with bench start command.

To verify it’s really issue pipe broken follow the below steps:

execute bench start command again. If it’s end with port number <8000> or is already in used then I am sure it’s cause by ssh connection lost only.

Also try below command and verify the redis, nodejs, python port number:
sudo netstat -ntlp:

tcp        0      0    *               LISTEN      1271/sshd

Can you show me output of sudo netstat -ntlp and sudo ps -aux | grep bench commands?

yes i understand i already mention above but this is not practical solution. Non technical user not able to follow everytime this process.

I got those issue after installing Python 3. I don’t know what to do now nothing work anymore

Any update on this issue

Based on the suggested issue on this thread. A reboot helped me.

USE this command
it’s remove the error
bench destroy-all-sessions
