Hi >From time to time I observe a deadlock in subprocess.Popen. I see the childprocess beeing <defunct> and if I attach gdb to the stuck python script, I can see it waiting on line 1128 in subprocess.py ( data = _eintr_retry_call(os.read, errpipe_read, 1048576) ).
Any ideas of whats going on? I'm on linux using python 2.6.5. I already found http://bugs.python.org/issue1731717 and stubbed out subprocess._cleanup, but this didn't really help and doesn't seem to be the problem anyway... A bit of information about what I'm trying to do: I try to control several process from a python script. Each process is started from a thread, the threads just wait() for the child to exit and can then be joined. Main waits for SIGINT. After it received the signal, it will send a signal to the processes spawned by the threads and then join() the threads (which should terminate after their process exits) Christoph -- http://mail.python.org/mailman/listinfo/python-list
