Description
When we receive out of order messages core crypto buffers them and throws one of these errors:
BufferedFutureMessage
Other("Incoming message is a commit for which we have not yet received all the proposals. Buffering until all proposals have arrived.")
Currently if you use the non-transactional API this means buffered messages will never be persisted since the underlying transaction is always cancelled when errors bubble up.
Solution
When decrypting messages use the transactional API and catch the buffer errors inside the transaction to avoid the transaction being cancelled since we actually want the changes, buffered messages, to be persisted.
