[issue35305] subprocess.Popen(['/sbin/ldconfig', '-p'], stdin=PIPE) itself hangs/deadlocks (Linux)

[STINNER Victor]

STINNER Victor <vstinner at redhat.com> added the comment:

I tested:

* Python 2.6.6 (installed from RHEL) on RHEL6
* Python 2.7.15 (compiled manually) on RHEL6
* Python 2.7.15 (installed from Fedora) on Fedora 29

Note: I tested RHEL 6.10 with kernel 2.6.32-754.el6.x86_64.

The fact that Python 3 is also impacted makes me think that it's a bug in your kernel, not in Python.


"MY CONCLUSION: To me, this looks like a deadlock in Popen() itself - is that correct?"

It works on all systems except of yours, I don't think that it's a bug in Python.

You have to debug your kernel.

This issue is not a Python bug, so I close it.

If you are a Red Hat customer, contact Red Hat to get support.
