[Spacewalk-list] yum not seeing updates

[Michiel van Es | Info.nl]

Hi,

I am havig trouble that some nodes doesn't seem to find any updates 
through yum.
When I check the files in :

/var/cache/rhn/repodata/centos5

I  see the following:
[root at fac03 centos5]# ls -lash
total 67M
4.0K drwxr-xr-x  2 root root 4.0K Jun 10 09:41 .
4.0K drwxr-xr-x 12 root root 4.0K Jun 12 06:18 ..

7.4M -rw-r--r--  1 root root 7.3M Jun 10 09:56 filelists.xml.gz.new
  28M -rw-r--r--  1 root root  28M May 16 03:27 other.xml.gz
  20M -rw-r--r--  1 root root  20M Jun 10 09:56 other.xml.gz.new
1.5M -rw-r--r--  1 root root 1.5M May 16 03:27 primary.xml.gz
1.2M -rw-r--r--  1 root root 1.2M Jun 10 09:55 primary.xml.gz.new
4.0K -rw-r--r--  1 root root  877 May 16 03:27 repomd.xml


What are the .new files? Shouldn't they be the new .gz files?
Could this be the issue I am having with yum update does not find any 
updates?
