> When trying to scale multiple RM clients to a single RM provider you find that after a period of time some of the clients do not receive their responses.
> The problem is that the InMemoryStorageManager uses a HashMap, which isn't synchronised.  When you have multiple clients with multiple sequences you have multiple threads trying to access the HashMap and therefore the problem. The solution is to convert the HashMap to a ConcurrentHashMap which is synchronised.
