it happened to me also ..... not on RHEL but Centos 5 ,

it's a kernel problem , I've googled a lot but vain ,and finally 
disabled the selinlux and now it is working fine, though it was not my 
production environment it was only test setup , so it was easy for me to 
disable the selinux ,

I'll not advice you to disable SeL.

Regards
