That's a bit surprising to me. It's usually concurrent calls that fail due to reentrancy issues of a non-reentrant module, not "subsequent calls". So while the concurrency case is quite possibly still a big problem, there might be something else going on, such as not initializing something that you are assuming is initialized. And if that was the case, your module is not only not reentrant but is not reusable. And that is unlikely to be what you intend.
