The GUI tried to access the TUXEDO System/T MIB to retrieve attributes of a Machine. This call has failed. Look at surrounding entries in the ULOG to determine the cause of the failure. This is a non-critical error and does not affect the GUI's functionality or performance. However, because of this error, the Progress Window of the ongoing Activation, Deactivation or Migration action, while displaying status messages, might display the LMIDs rather than PMIDs for some sites in the application.
