 I cannot reproduce that at all (on x86_64).

[root@shutdown ~]# rpm -qf /usr/sbin/ss

 [root@atlas ~]# rpm -qf /usr/sbin/ss
iproute-2.6.18-9.el5

[root@atlas ~]# yum install iproute-2.6.18-9.el5.x86_64
Package iproute-2.6.18-9.el5.x86_64 already installed and latest version

I make upgrade from CentOS 5.2
[root@atlas ~]# rpm -qa |grep iproute
iproute-2.6.18-9.el5

 That still does not make it reproducable.

I tested on several machines now, 32bit and 64bit - none of those show a segmentation fault.

 close(4) = 0
open("/proc/net/tcp6", O_RDONLY) = -1 ENOENT (No such file or directory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---



May be because u have enable ipv6

 Yepp, that was it. With ipv6 turned off, I can reproduce that segfault.

This should be reported upstream at https://bugzilla.redhat.com/ [^] - if you do that, please reference this bug in the "third party bugtracker" item and give us the link to that bugreport. I have searched, but didn't find any reference to this bug. If you don't want to report it upstream yourself, I can do that for you.

You decide.
