Periodically ORA-600  errors are raised when executing an INSERT or MERGE command which has previously been executed without error.
Checking V$SQLAREA and V$SQL_SHARED_CURSOR for the failing statement shows a large number of cursor sharing failures due to insert direct load mismatches (INST_DRTLD_MISMATCH=Y), e.g.:
connect / as sysdba
select s.version_count, s.users_opening, s.users_executing, c.*
from v$sqlarea s, v$sql_shared_cursor c
where s.address = c.kglhdpar
and sql_text = '<Your SQL statement>';
