dentry_cache that wasn't being reclaimed. Probably a bug in the old version of the Linux kernel that this server is using. The solution that worked for me was:# sync && echo 2 >/proc/sys/vm/drop_cachesIf you're curious as to what this does, RTFM.

Did you figure out a fix for this? I have the same problem on my centos 6 box and it's unacceptable!
There is a thread about this problem on the redhat mailing list:

Is this the same problem you are seeing?
I upgraded this box and no longer see the issue, so I never really took the time to get to the bottom of this. I actually stopped using CentOS. Probably the newer kernel that came with the new distro doesn't have this problem/bug.
