I confront a problem while porting my python program in AIX.

The problem seems on ownership or permission between processes.

Let's assume that there are two processes(process1, process2).

The processes are in the different process group.

In this situation the Os Error happens when the process1 try to get pgid of procees2 returning Not Owner OsError.

The problem never happen in Ubuntu(Linux)

Please give me any suggentions.

How can I solve this problem?

    getpgid is allowed to return EPERM when you try to get the pgid of a process that is not in your process's session. So one way to avoid this is to make sure the processes are created while in the same session. Jul 19, 2016 at 16:29
  • @Mark Plotnick : If there is another way by settings OS settings (Permission or something)
