왜 root 가 3개죠?

pid 13054 인 root 하나만 있으면 될것 같은데~ 3개인 이유가 궁금합니다~ (~_~)~

그리고, 번외로

/var/log/memssage 에 한시간에 한번씩
Apr 23 10:40:21 localhost : error getting update info: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
Apr 23 10:49:27 localhost restorecond: Will not restore a file with more than one hard link (/etc/resolv.conf) Invalid argument

이러한 로그들이 쌓여서 yum을 check했더니

[root@localhost log]# yum check-update
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
http://ftp.daum.net/centos/5/os/i386/repodata/repomd.xml: [Errno 12] Timeout: <urlopen error timed out>
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again

이렇게 되네요 -_-;;

해결방법좀 알려주세요~

참고사항..

* /etc/resolv.conf

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
