If you have the kernel 2.6.18-128.1.10, or later (you can check by typing
"uname -a" in a terminal window.), you have 5.3 already. It was released in
January, and comes with the normal RHEL 5 update process.
I looked in the release notes for 5.3, and it doesn't seem to mention Xvfb at
all.
I suspect there still may be a bug in Xvfb. If you have already tried 5.3, and
still have this problem, you may want to try a POSSIBLE solution that Evan
Lowery(elowery@xxxxxxxxxxxx) has found - using IDV2.7b2 on a 32 bit system with
Java 3D 1.3 (compatibility mode)
You may want to check with Evan and/or Unidata first, since I said before - I
have not been able to find a solution to the Xvfb problem (other than running
IDV scripts thru the Console)

Hi Samuel,
Thanks very much for the reply. I will definitely look into upgrading to 5.3
and will report back what happens. I agree, setting up virtual machine is not
really something that I believe is possible for us at the moment. The weird
thing is that it runs fine on CentOS5 which seems a little odd.
Ultimately, the Xvfb is a temporary solution until I can identify what is
causing ISL scripts to fail when offscreen is set to true.
Thanks again for the help Samuel and I will keep the list updated w/any
progress I have.
Cheers,
Matt

The situation I ran into was not a hardware issue, because I could run the .isl
script at the console with no problem. Only Xvfb would fail(with a segment
fault).
My belief was that RedHat introduced a bug to xvfb when moving to RHEL5, since
RHEL3 seemed to work fine. I submitted this issue to RedHat, and was told that
this would be fixed in RHEL 5.3.
I have not been able to test the 5.3 fix, however Matt makes it sounds as
though it may still be an issue. If you haven't upgraded to 5.3, please do so,
and let us know how it goes.
RedHat technical support also suggested using a Virtual(XEN) machine to run IDV
with the .isl script, until RHEL 5.3 was released. Unfortunately the amount of
time/effort required to convert our server to XEN is prohibitive. It also
seems like using and elephant gun to kill a flea. I was going to wait until
5.3 came out, but the xvfb problem has now become a low priority at our site.
