Default Multiple GLIBC loaded

Hello,
We have a shared object common.so built on RedHat 6.2 ( kernel
2.2.14-5.0 ) with GCC egcs-2.91.66 and GLIBC versions as below.

$ rpm -qa | grep glibc
glibc-devel-2.1.3-15
glibc-2.1.3-15
compat-glibc-5.2-2.0.7.2

The binary when executed on a Red Hat Enterprise Linux Server release
5.1 ( kernel 2.6.18-53.el5 ) GLIBC versions as below.

$ rpm -qa | grep glibc
glibc-2.5-18
glibc-devel-2.5-18
glibc-common-2.5-18
glibc-headers-2.5-18
glibc-devel-2.5-18
glibc-2.5-18


I find my threads deadlocked by use of multiple versions of GLIC, is
there a way to get around to use one version of GLIBC ?
I would prefer not to re-build on a RH5 box as this would be a big
effort for us. Any workaround possible on our old build box RH6.2 ?

Thanks and Regards
