That's always likely. The release notes were written at a point in time
where RH 9 was only just becoming available (and even Fedora Core 1 was
just a beta). It's a lottery with the Linux distros - you don't know what
you've got until you install it. People tend to settle on a favourite and
then do all the upgrades.

Basically, if the server runs, then those libs are OK.

There is linuxquestions.org, if you want to ask about known bugs in RH
9. It was the first of the "mainstream" distros to have NPTL. It could be
that it has a threading bug causing some problem when a process thread
detaches...I don't think the RH 9 free binaries have any sort of
maintenance (it was the last-ever free Red Hat); but if you have a paid
version, Red Hat's support people should be able to point you to an update
pack. (FWIW, I recall Paul Beach having a lot of problems with Red Hat 9
at a customer site..)

It might be like looking for a needle in a haystack. You could "take the
low road": make the settings described in the 1.5 release notes and revert
the system to the older threading model. AFAIK, the NPTL build of Firebird
will work with the old threading; otherwise, just uninstall it and
re-install the regular build.
Also, Firebird 1.5.2 is about to be released, perhaps you could try that.
