    Note By default, the time-out interval is 300 seconds.
  • You use Antigen to download the engine. However, the download process is not complete by the time that n seconds have elapsed.
  • Antigen waits five more seconds after n seconds have elapsed, and then Antigen evaluates the download process.

MORE INFORMATION

By design, Antigen uses the following procedure to handle a time-out in the engine download process.

Note In this procedure, the time-out interval is set to n seconds.
  • Antigen starts the download process.
  • If the download process is not complete by the time n seconds have elapsed, Antigen waits five more seconds and then evaluates the download process.
    • If the download process has not progressed in those five seconds, the download process is reported as a time-out.
    • If the download process has progressed in those five seconds, the download process continues. Antigen evaluates the download process every five seconds until another n seconds has elapsed (for a total of 2n seconds).
      • If the download process is not complete before 2n seconds have elapsed, Antigen reports a time-out, and the download process is canceled.
      • If the download process is complete before 2n seconds have elapsed, Antigen should accept the new engine.

        Note The issue that is mentioned in the "Symptoms" section occurs in this step.
