We have to servers (Win2003/Oracle 10g) with materialized-view replication. There are two groups configured, "normal" and updatable mviews. Refreshing the normal mviews works without problems.

When we try to refresh the updatable mviews, there is an error (until last week it worked for more than two years):

ORA-23324: Fehler ORA-03117: Two-Task Speicherbereich übergelaufen
ORA-02063: vorherige line von TDMT4000.BAD01.DREIEICH.TICOS.CH
ORA-01403: Keine Daten gefunden beim Erstellen von deferror-Eintrag auf
"TDMT4000.BAD01.DREIEICH.TICOS.CH" mit Fehler 100
ORA-06512: in "SYS.DBMS_SNAPSHOT", Zeile 2251
ORA-06512: in "SYS.DBMS_SNAPSHOT", Zeile 2457
ORA-06512: in "SYS.DBMS_IREFRESH", Zeile 685
ORA-06512: in "SYS.DBMS_REFRESH", Zeile 195
ORA-06512: in Zeile 2

(sorry for the german error, but the ORA-numbers are identical)

is there any help about that?
