Hi, It might be: - a memory corruption issue. Make sure you are running the latest release of rpy2 (you do not specify what you are running) - concurrent access to R (R is really not cool with that). Rpy2 is trying to prevent it with a system of locks (since the errors one is getting are otherwise quite cryptic and hard to associate with that), but there might be other ways. Check if there are differences between dev and prod regarding multithreading. - ending the embedded R and restarting it later. R is again not cool with it. I guess rpy2 should just have a way to throw an error if tried (I thought I did add it, may be I didn't).
