Today I have been reported from the next error in a Oracle 10.2.0.5 version;
ORA-00600: código de error interno argumentos:   [0x570A6ED78]     
Looking at MOS, I have discovered that it is the bug 8449495. The error is raised when client side process die or break the connection, when execute a fetch from SQL which uses pipelines, the server side report this ora-00600.
This bug has been fixed in 18.104.22.168 Release. You can too apply a oneoff using patch 844945. However in this case you can safely ignore the problem because it since report an error when the connection is been closing.
