I got a rather large message in terms of many fields in a message:

int64 id

string componentname

string type

int64 parent

string parenttype

builtin_interfaces/Time stamp

int32 advertisementtype

int64[] childids

string[] childtypes

int64 machineip

I recognized while testing with opensplice as middleware that in some transfered messages the last fields are empty. For example machineip is in most cases 0. The field at the beginning of the message are transfered correctly.

Is this a bug or specified behaviour ?
