Recently installed the funambol Server app on my RedHat6 Set up. Instalation went fine but when i tried to start the server i got the following error message

dl failure on line 716Error: failed /root/Sync5j/tools/jre-1.4.2/jre/lib/i386/client/libjvm.so, because /root/Sync4j/tools/jre-1.4.2/jre/lib/i386/client/libjvm.so: symbol sem_wait, version GLIBC_2.1 not defined in file libpthread.so.0 with link time reference.

I'm guessing this error is refering to the java virtual machine which i think is what this app runs off. Also refers to GLIBC so is it telling me that my GLIBC is out of date or is missing some files?
Any help would be great as i really want to get this server up and running.
