Hi Jay
Thanks so much for your reply - I do actually have my hostname in
/etc/hosts - the wierd thing to me is that (I should have mentioned in
my previous post) I was getting no such delay on FC3-32 on the same
hardware - but with FC3-x86_64 the delay is present.
Did you run the command? What was the output?
