FileMaker Server 10 admin console refuses to load

Well... that was interesting.

This was the scenario when I arrived at the office this morning:

1. One database on our FMS 10 server was accessible just fine.
2. The other one was not. Trying to access it made FileMaker Pro 10 hang (icon kept spinning).
3. Trying to load FMS admin console resulted in some error code which unfortunately I did not record. I think it had to do with Java. This was on my workstation
4. On the server machine itself, trying to start the admin console resulted in... nothing. It opened, and promptly closed without fanfare.

Resolution (on Mac OS X):

1. I manually stopped and re-started the FileMaker Server processes:
1. Open the terminal.
2. Type "sudo launchctl stop com.filemaker.fms".
3. Authenticate.
4. Type "sudo launchctl start com.filemaker.fms".
2. Voila'! Well, not quite. Now the admin console was giving me the same error on the server machine.
3. Reboot.
4. Voila'! This time, really truly! :-)
