Most likely, the database server has disconnected the database connection and now ->connect_cached tries to reuse the connection but times out. Consider speaking with your database administrator and network administrator after what time the database and the network will drop an existing connection.

Another problem can be if you use the fork system call. Ideally, DBD::Oracle (and the underlying database library) would detect that and reestablish the connection, but maybe they don't and try to reuse the connection of the parent.
