Correcting errors in data objects includes executing a main process to process the data objects, detecting an error in a first data object via the main process, sending, to an error correcting process, the data object and information associated with the error, and instantiating an instance of the error correcting process to attempt to correct the error. The error correcting process is implemented using substantially a same environment as the main process. The main process continues to execute during and after sending the data object and the information to the error correcting process and while the error correcting process attempts to correct the error.
