Thanks for the info!

Doing a full update from the rpm's at :
https://rhn.redhat.com/errata/RHSA-2003-325.html

[root at localhost downloads]# rpm -Fvh glibc-2.3.2-27.9.7.i686.rpm
glibc-common-2.3.2-27.9.7.i386.rpm glibc-utils-2.3.2-27.9.7.i386.rpm
glibc-debug-2.3.2-27.9.7.i386.rpm glibc-devel-2.3.2-27.9.7.i386.rpm
nptl-devel-2.3.2-27.9.7.i686.rpm

seems to have done the trick on my machine. No OSL crash this time.

Thanks,
Matt
