Hi,
ora-600s are very strange errors, and most times difficult to understand.
there are however some useful notes.
ORA-600/ORA-7445/ORA-700 Error Look-up Tool          [Article ID 153788.1]
Master Note for Diagnosing ORA-600          [Article ID 1092832.1]
besides that, you could inform us of the platform, OS, DB version that you are using.
