Hi.
Has anybody faced the following problem with OIM 9031 at JBOSS 4.0.3 SP 1?
The system scheduled task named 'Re-issue Audit Message Task' is configured to launch each midnight, and generates the following error, after which the application server (and OIM) hangs:

2008-02-16 00:00:02,108 ERROR [XELLERATE.DATABASE] Class/Method: tcDataBase/writeStatement encounter some problems: ORA-01400: can't insert NULL in ("OIM_USER"."UPA_USR"."USR_LOGIN")

java.sql.SQLException: ORA-01400: can't insert NULL in ("OIM_USER"."UPA_USR"."USR_LOGIN")
