We use a server at work that is patched RH 7.3 / 2.4.18 with 2.4.21 (or
thereabouts its < .24).
We have stability issues with Java 1.4 / Tomcat 4.1 but not Pg.
It might even be worth building yourself a vanilla 2.4.18 kernel and
seeing if that makes any difference...

No, but you chould check for those fields and return if no changes have been
