Description

Summary scenario

  1. Application gets an exception
  2. ES restarts the application
  3. There is a high probability that the application checksum has changed due to the restart.
  4. Checksum is not notified to recompute the application checksum. When it finds the checksum has changed, it puts out an event message to that effect.
  5. HS is monitoring for application checksum messages, and does a processor reset as a consequence.

Research direction

Start by tracing the application restart path described in the issue, then inspect how checksum recomputation and checksum event messages are handled between ES and HS. Done means a restart reliably triggers the checksum notification and the resulting processor reset behavior is verified; the payload names no files or tests.
