Comment 2 Jiri Popelka 2011-10-31 15:49:47 UTC

bz634539-netstat-c-has-a-memory-leak
is a regression test but I get the same results when running it with
net-tools-1.60-102.el6.s390x.rpm (shipped with RHEL-6.0) and
net-tools-1.60-105.el6.s390x.rpm (shipped with RHEL-6.1),
so it's not a regression in netstat (net-tools).

Either the test was always failing on s390x (and then it's the test what needs to be fixed)
or from the log it seems as a problem with glibc-2.12-1.46.el6.s390x

Steps to Reproduce:
1. valgrind -v --leak-check=full --show-reachable=yes netstat -c
2. wait a few seconds and press ctrl+C

Actual results:

Comment 7 RHEL Program Management 2012-07-10 06:48:57 UTC

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Comment 8 RHEL Program Management 2012-07-11 01:54:21 UTC

This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
