If restoration of packages fails then CentOS. The problem does not appear to be with Python directly:
# rpm -qf /usr/lib64/librpmbuild-4.4.so
rpm-libs-4.4.2.3-28.el5_8.x86_64

It is impossible to say what else may have been damaged, but there appears to be a problem with rpm-libs. Try
rpm -V rpm-libs
then perhaps
rpm -Va
but I suspect rpm may be too damaged for even those to work.

Hi Phil

Do you mean a fresh install of python? Or a fresh CentOs install?

Many thanks

Welcome to the CentOS fora, and congratulations on being one of the select few to do the recommended reading before posting.

I'd strongly suspect New Relic, but why did you obscure important and non-sensitive information like the kernel version?

You may be able to recover by reinstalling the packages/libraries clobbered by New Relic from rescue mode, but a fresh install is probably the cleanest route to a stable system.

Since my previous comment I have cloned my server to experiment and now I am getting the message below. It looks like this was updated yesterday. any ideas how I can repair this?

Many thanks


There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

/usr/lib64/librpmbuild-4.4.so: invalid ELF header

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.4.3 (#1, Feb 22 2012, 16:05:45)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-52)]

If you cannot solve this problem yourself, please go to
the yum faq at:
http://wiki.linux.duke.edu/YumFaq

Hi

When I try to run the commands wget, rpm or yum I get the error 'Segmentation fault'.

The application on the server is still running fine. I would really appreciate any help on this as I want to avoid disrupting the application.

I have Centos 5.8, PHP 5.3.1 and I installed New Relic yesterday. This problem started 5 hours ago.

Here is the info:
