This has proven in the pas to be a NIC misconfiguration or a network issue. I think that is what it is on this one too. Is there a way when I see an app haning at boot to make the server stop trying to load the hung app and bring the OS up into the GI so that I get to fixing it? Thanks in advance.
Usually they are just waiting on a DNS timeout so if you wait long enough you'll
get the login prompt (but you'll have time to go get some coffee or
something). If you get tired of waiting you can reboot with a ctl-alt-delete
and as it comes back up, hit a key to get the boot prompt, pick the kernel you
want to boot, hit 'e', then select the kernel line and hit 'e' to edit and add
'single' to the end of the line, and 'b' to boot it. That will bring it up in
single user mode without starting the network or most of the services. You'll
be in command line mode but you could probably use 'startx' to bring up the GUI
desktop if you wanted.
