Dear gurus !

We are trying to analyze a table partition (estimate 2 %) and it takes forever.
analyze table ... partition (P20021022) estimate statistics sample 2 percent;
For instance, select count(*) from the same partition takes 10 minutes , but the analyze takes literally infinite amount of time , once i left it to run for half a day and killed it since it did not finish. Even when i do analyze ... estimate statistics sample 100 rows; , it takes almost 2 minutes to ananlyze 100 rows.
Any ideas ?
It's Oracle 8.1.6 on an expensive 6 CPUs HP machine with EMC storage. Thanks a lot in advance.
