Yes -- same platform and version. If you look on the list archives (fatcity.com, for example) for a subject of "Burned by DBMS_STATS **AGAIN**" back in April 2003, you may get some insight.
There are also known bugs in GATHER_SCHEMA_STATS in 8i. The recommendation is to iteratively call GATHER_TABLE_STATS. GL!

Saw a note in Metalink that its better to do the above with 'cascade=>false' and then do a gather_index_stats separately. In my tests, I see that 'analyze' makes the CBO use an index while dbms_stats is making the CBO to use a FTS instead. Have you faced any similar issues?
