to figure out what is dropped we used vempkt capture but we dont see packets.
Here the session output:

DS-N1K-10# module vem 3 execute vempkt stop
Suspended log
DS-N1K-10# module vem 3 execute vempkt display detail all
Also the exported capture file is empty:
DS-N1K-10# module vem 3 execute vempkt pcap /tmp/vempkt_capture_drop.cap
Export Complete!
DS-N1K-10#
Is there a way to find out what is dropped?
