DB Link gives ORA-600

I have a 9.2.0.4 database which is connected to another through db link.
Every day at specific time i'm receiving the following error in the alert file:
"ORA-00600: internal error code, arguments: [729], [104], [space leak], [], [], [], [], []
ORA-02068: following severe error from <name_of_db_link> ORA-03113: end-of-file on communication channel"

The trace file that accompanies the error does not include any other details.
The second db is up and running,neither is backed up at that time and the time is such that hardly anybody of the users is connected to the database.

Has anybody faced anything like this before? Any ideas will be appreciated.

Thanks in advance,
