(IMHO) Oracle ORA-00600 errors should be considered off-topic here because they're internal errors and there's very little we can do to diagnose and help people with them. The recommended and best way to get them resolved is to raise a support request with Oracle.
Assuming the consensus is that ORA-00600 questions are off-topic:
Can we add text to the effect that ORA-00600 errors are off-topic and that the asker should contact Oracle support?
More generically, the text could be added to the bullet list under dba.se is not the right place to ask questions about..., something like:
- DBMS internal errors. In particular, if you have an ORA-00600 error, contact Oracle support.
Can we even check for ORA-00600 when asking a question and warn about these being off-topic?
