> the LargeServerMessageImpl.asLargeMessage will check if the message is beyond the journal buffer size and convert it to large.
> if retention is used, this operation tries to make a sync operation on the journal which will never complete because is being called within the JournalExecutor itself. It's a server's deadlock on this case (actually technically a starvation, but same results).
