Do you mean "no x2 hand over attempts or no of x2 handover attempts"
I think it is about "no X2 handover attempts".

When X2 link is established between two eNodeBs. One eNodeB can ask other eNodeB to report resource status. Before initiating X2 handover, source eNodeB considers target eNodeB resource status and then take decision on handover. Other than this, I don't think so any other reason which results not to trigger X2 handover.

In case of hub-and-spoke topology, X2 messaging can travel all the way back to an aggregation point, which may be co-located with EPC. In such scenario both X2 and S1 traverses same physical path (a.k.a X2 over S1). Please consider both Intra-MME and Inter-MME handover scenarios. Would X2 based handover in such a case yield advantage over S1 based handover. Thanks.
