Issue #9525 has been updated by Motohiro KOSAKI.


I checked a glibc code. I don't think fa3fc0fe5f fixed this issue. It is a mere optimization patch.
I'm not sure why kernel's netlink doesn't reply anything. But it may be worth to try upgrade your kernel.

Thanks.

We met this trouble with Fluentd https://github.com/fluent/fluentd. 

Fluentd is sometimes stuck at `Socket.pack_sockaddr_in` line on shutdown.
