This problem seems to be a result of NPTL (Native POSIX
Thread Library for Linux) that comes with Red Hat 9. Try setting the
<a href="http://people.redhat.com/drepper/assumekernel.html"
   target="extlink">LD_ASSUME_KERNEL</a>
environment variable before starting OGo:
<pre>
export LD_ASSUME_KERNEL=2.4.1
</pre>
If that doesn't solve the problem, please provide feedback on the users
