ora-600 when analyzing IOT

Ok, since my original message still hasn't arrived (sent couple hours ago), here it goes again (sorry, if you get duplicate).

First, sorry for asking this list before searching Metalink, but I don't have access to it right now.
So, here it is:

I'm getting:

ORA-00600: internal error code, arguments: [15163], [333], [17424], [16191], [], [], [], []

when analyzing one of the index-organized tables:
"ANALYZE TABLE ipn_measurement ESTIMATE STATISTICS".

Now, similar statement analyzing other IOTs works fine.

Also, on the same table (ipn_measurement) analyze worked fine yesterday, and the table didn't grew too much since yesterday.

Any ideas?

Another question, do I really have to run "analyze table" on IOT for cost-based optimizer, or analyzing index would be enough:

"ANALYZE INDEX pk_ipn_measurement ESTIMATE STATISTICS"

because "analyze index" still runs with no errors.

Oracle version is 8.1.5.
