I'm not sure if it's before or after your changes, Poul-Henning. If there is a newer -RELEASE I can upgrade too, I will do that. I don't really want to upgrade to -STABLE, but I will also do that to relieve the issue if necessary. Just give me a recommendation on to either update RELEASE beyond -p1 or to go ahead and update to -STABLE. I appreciate the help all of you have been. Thanks much.
