11gR2: Find Source of Locked Table Statistics

Hello Friends,

When calling ANALYZE TABLE ... ESTIMATE STATISTICS, our customer is occasionally getting the following error:

ORA-38029: object statistics are locked Error executing the following SQL:
ANALYZE TABLE "CMPT_25453" ESTIMATE STATISTICS --->
Oracle.DataAccess.Client.OracleException: ORA-38029: object statistics are locked

After reviewing document 433240.1, I see that the cases where statistics are locked are fairly limited:

#1: DBMS_STATS.LOCK_[SCHEMA|TABLE]_STATS has been used to lock statistics on the table.

#2: Using import (imp) or data pump import (impdp) to import a table without data results in the table's statistics being locked in 10gR2.

#3: If the table is a queue table then the statistics are intended to be empty and locked so that dynamic sampling will be used due to the table's volatility.
