Dear,

=C2=A0

Thank you for the information !

I rerun the primary application with the other termi= nal running=C2=A0pdump, however it still can't capture the packet.

As for the logs you mentioned that is printed after = the primary application terminates. Also, for the primary application log, = I can make sure it transmits and receives the packet, but pdump still can&#= 39;t capture it.

=C2=A0

[Reshma]: Are the pcap captured files empty?=C2=A0 T= hat might need some debugging I guess. When you stop the pdump application = you should see below stats. =C2=A0

If you see 0 =E2=80=9Cpackets dequeued=E2=80= =9D, that means there is no Packets received from primary to pdump applicat= ion.=C2=A0
