Trying to identify a design pattern

I am currently working with an inherited piece of code that uses a very interesting design pattern.

The code is split into a number of objects. I am not sure if the term object is applicable since it is a C code, but it is the best analogy. Each object has object-specific data, a thread, and a message queue. All objects primarily communicate by placing pre-defined messages onto each-other's queues. The main idea seems to be is that each object's data is only accessed by one thread. After doing some research I discovered that a few industrial automation applications are written this way (namely the ProfiNET stack and some EIP implementations).

Do you know if this pattern has a name or if it is describes somewhere in the literature? The "Pattern-Oriented Software Architecture" book by Schidt, Stal, et al does not mention it.

Thank you very much.

This sounds somewhat related to the Actor model.

Check out Communicating Sequential Processes (CSP)

CSP allows the description of systems in terms of component processes that operate independently, and interact with each other solely through message-passing communication

It is actually one of the core design concepts that the Go language is based upon for communicating between goroutines (concurrency).

It might be me but is any other pattern except producer consumer combined with mutual exclusion used in what you described ?
