Not very helpful to me but hopefully you can understand it. To me the puzzle is why does an attached console make any difference?

No, but the oracle might.

Credentials cache I/O operation failed XXX

Cause:

Kerberos had a problem writing to the system's credentials cache (/tmp/krb5cc_uid).

Solution:

Make sure that the credentials cache has not been removed, and that there is space left on the device by using the df command.

Might be permissions Credentials cache I/O operation failed XXX (with 1.5.x on Windows 2003 Terminal Server)?
