The EoN sends NDATA payloads.
The Device is allowed to send DDATA payloads (by/through command of the EoN)
It seems that the DDATA payloads are tagged with a SeqNum that is too high (it needs to be N, but is tagged with N+1)
This incorrect tagging (N+1) causes/triggers the Server Node to issue a DBIRTH NCMD.
This results in a Sparkplug EoN Node that is in a continuous cycle;
Improve "assigning of seqnums to payloads" by implementing a mechanism to tag payloads "just in time" with a correct seqnum. This ticket also has a certain relation with "Improve control of/over/with statemachine [#93]"
