[CentOS] Three kernel RPMs at same time and yum error: "sem_post: Invalid argument"

I just ran "yum update" on a remote 4.2 Centos install. Then I typed
"yum search some package" and got this error message repeating

sem_post: Invalid argument

A search for this message revealed only these links:



If I run the command to look for duplicated RPMs described in those
pages I get:

-bash-3.00# rpm -qa | sed 's/\([A-Za-z0-9]\)-[0-9].*$/\1/' | sort | uniq -d

As a matter of fact, I also get:

-bash-3.00# rpm -q kernel

My question is, what is the best, safest way to fix the system?

The hack described in those pages doesn't seem (to me) to apply
directly to my case. Being the kernel involved, instead of normal
packages, I'm hesitant to try something that, as far as I know, may
bring this remote server in an unusable state.

Any help is appreciated.
