I have similar problem with pcaps, but in my case pktgen doesn't send anything after "start 0".
Nothing happens after "start 0". Counters doesn't increments.
Without pcap all works fine. Before that I used very old version pktgen-3.0.02 (with DPDK 16.04) and pcaps works on it.

From startup logs:
./pktgen -l 0-3 -n 3 -- -P -m '[1:2].0' -s 0:./pcap/test.pcap

PCAP file for port 0: ./pcap/test.pcap
  magic: a1b2c3d4, Version: 2.4, Zone: 0, snaplen: 65535, sigfigs: 0, network: 1 Endian: Little

Create: PCAP TX     0:0  - Number of MBUFs      4 for     3 packets                 =      7 KB

Tested on:
DPDK 18.11 and DPDK 18.08
pktgen-3.5.9

It's problem with small pcaps. Small pcaps are not sent.

I'm using dpdk-18.11 and pktgen-dpdk-pktgen-3.5.9

Actually, I have another problem and that is pktgen fails to start when I want to use big sized pcap file. I tried with pcap of 21GB size.
