Abstract: A system adapted to process long-running processes is disclosed. A request to upload data is received at a server. The server divides the data into multiple parts and launches a separate process to upload each of the divided parts. The server records for each process the processing time or duration that the particular process used to upload its corresponding data item. The server maintains an average processing duration that is calculated from the processing durations of the completed processes. The server identifies that one process is continuing to run and compares a processing duration for the particular process to a threshold derived from the average processing duration. If the processing duration for the particular process exceeds the threshold, the server initiates a new process to upload the same data item. When one of either the new process or the still running process has completed processing, the server terminates the other process.
