.refresh() problem

Hi.

I had been running JIRA on a linux box (redhat 7.2) with tomcat 4.0.3 and
postgresql 7.1. We just upgraded the box to redhat 7.3 which included an
upgrade of postgresql to version 7.2.1 There were no changes to the jdk or
to tomcat. The performance of JIRA on tomcat wasn't so great, so, I
decided to try JIRA on orion. Wow! It runs great and is as speedy as can
be! Unfortunately, I have run into a bit of a problem with posgres and
orion. I can create issues and perform administrative tasks but I cannot
update any issues. If I try to add comments, resolve, reopen, edit, or
attach I get an error similar to the following in my web browser but nothing
out of the ordinary in the console:

java.lang.IllegalArgumentException: [GenericDelegator.refresh] could not

I can perform these tasks without problems (except for being really slow)
using tomcat as the web application server with the same database and jdbc
driver as with orion.

Is anybody else using JIRA with postgresql 7.2.1 and orion 1.5.4? Any ideas
what might be causing the error and what I can do to resolve it?

Thanks,
