  • This change aims to prevent the server from hanging when a Python backend model fails to initialize. It replaces an indefinite wait for a message from the stub process with the ReceiveMessageFromStub function, which correctly detects errors from the stub process.
  • Additionally, it fixes shm cleanup when a model fails to initialize (DLIS-8432).

Found a bug that the Python backend internal SHM is not destroyed upon model initialization failure, and have created an internal ticket DLIS-8432.
