Description of problem:
during yum transaction glibc cleanup stalls and a ps shows it is stuck running redhat_lsb_trigger.
# ps auwwwwxf|grep lsb

Version-Release number of selected component (if applicable):
I just ran into the same thing here, except in my case after the glibc.x86_64 trigger segfault, it hung on updating glibc.i686 and I had to hard reset the machine.
In case that's not clear, this bug makes redhat_lsb_trigger consume all system resources, till the system stops responding (if you're lucky the noise made by the HD as the system starts swapping like mad alerts you there is a problem and you can kill the redhat_lsb_trigger process before the situation goes critical)
Here /usr/sbin/redhat_lsb_trigger.x86_64 simply segfaulted twice during yesterday's "yum upgrade", but the upgrade otherwise finished. No high load or other problems seen besides that message.
