> 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).
