ORA-03001: unimplemented feature. How to find the reason.

Question

RDBMS version: 10.1.0.5.0
Sometimes our application raise the error ORA-03001.
We need to get more information about the problem because we are not able to find the reason of this error.
Someone suggests me to set the event:
alter system set event = '3001 trace name ERRORSTACK level 3' SCOPE=SPFILE
What do you think about it?

First of all the SCOPE=SPFILE will require to bounce the database. You might first consider setting and testing the event in Memory.
Then you can run a little script to see if the error is trackable and if the tracked information is useful.
