I'm running a CentOS 6/x86_64 system with all updates.
The yum config points at a local CentOS repo mirror:
[base]
name=CentOS-$releasever - Base
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=ftp://clustersw-212.mayo.edu/CentOS/$releasever/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
(same idea for "updates", "extras", and "contrib" repos)
Running:
# yum update
Failed to set locale, defaulting to C

If I do an strace:
gettimeofday({1345149621, 565646}, NULL) = 0
clock_gettime(CLOCK_MONOTONIC, {83862, 679396531}) = 0
socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 8
fcntl(8, F_GETFL) = 0x2 (flags O_RDWR)
fcntl(8, F_SETFL, O_RDWR|O_NONBLOCK) = 0
connect(8, {sa_family=AF_INET, sin_port=htons(40181), sin_addr=inet_addr("129.176.212.87")}, 16) = -1 EINPROGRESS (Operation now in progress)
clock_gettime(CLOCK_MONOTONIC, {83862, 679916402}) = 0
poll([{fd=8, events=POLLOUT|POLLWRNORM}], 1, 29975
(hangs there until timeout)
(129.176.212.87 is the correct address for clustersw-212.mayo.edu)
The repo server works fine for all other clients using it and there's no
issue network-wise getting from this machine to the repo server.
With all the timeouts, the "yum update" takes approx 1.5 mins to complete.
I suspect this is some sort of issue with libresolv and/or all the patches
RHEL has come out with recently regarding turning off IPV6 kernel modules
(we're not using IPV6, nor round-robin on DNS servers).
Has anybody seen these symptoms before and if so, what's the cause/cure?
Thanks--
