Manual cleanup of Recovery Catalog table ROUT

We have an Oracle Enterprise Edition version 11.2.0.3 recovery catalog and have noticed that the table ROUT contains over 90 million records.  We are experiencing issues when trying to resync the catalog since the resync issues a delete statement on that table, and if a particular database has many records in there it can fail for max extents on rollback segment.

RMAN> resync catalog;

starting full resync of recovery catalog
