"Desc " failed, does it exist? error

I am getting the following Runtime error when I first log onto my
application:

"Desc " failed, does it exist? error

Notice the space after Desc…not a typo…it appears it is losing
tablename somehow when attempting the Desc. Once I refresh the browser,
the page comes up fine.

I found information regarding Ticket #11134…however the error still
persists after applying the changes to oracle_adapter.rb and rebooting
the Mongrel cluster. I’ve tried setting allow_concurrency to both true
and false and no difference. This only happens running Mongrel cluster,
if I run one instance of Mongrel everything works fine. We are running
Rails 1.2.5 with Mongrel cluster 1.0.4. Any suggestions?

Thanks,
Brian
