stecal, export terminated successfully...

Now I'm getting the following error while importing AQ_MANAGER's objects:

------
. . importing table "MSG_MULTI"kgefec: fatal error 0

IMP-00058: ORACLE error 21503 encountered
ORA-21503: program terminated by fatal error
IMP-00028: partial import of previous table rolled back: 89809 rows rolled back

-----

Would this be a serious error? Could it be ignored?

Many thanks.
