nohup doesn't work for running the MadGraph5 on the remote terminal

Hi,

Recently I want to run MadGraph5 on the remote computer (ssh) through nohup.
my command is: nohup ./bin/madevent ttjj_run
where in the script ttjj_run, the command line is:
 multi_run 100
2

But there is an error information:

  IOError : [Errno 9] Bad file descriptor.

What is the problem here? Is there another way to realise the goal that when I terminate the connection, the MadGraph5 is still running.

Best wishes,

Da

PS: I also post the run_02_tag_1_debug.log file as follows:
