One thing that should be done incrementally is making sure each error path has a unique LOG_ERR(). I found several error paths that would give us the same return value and LOG message which was confusing for user and agents (in fact the agent added its own temp logging to find the actual error).

Agree. I also came across such places in the code. I am going to keep that in mind while providing further IPC related fixes.
