with dnx0.19a the service output can get truncated if not followed by a carriage return.
I have one service that normally reads something like
OK: Interface Serialx(index 5) is up.
The service check does not include a CR. If I run this service locally, it works fine. If it is returned via dnxClient, the up. on the end is missing. If I mod the check to add a CR, the up. is there again...
