Well, no, I can't recommend one. You are running Enterprise Linux,
right? Just make sure that you have upgraded to the latest version
possible. Hopefully that won't have that particular problem... (if my
guess was right, of course, the symptoms sound similar to the old
problem I mentioned but I can't be sure). 

You don't want to upgrade such a basic component as glibc to anything
that has not been released for the specific version of the linux
distribution you are running.
