When we  see stream module is dropping packets,  please do the following to figure out which stream event is doing this:

1) #vsh connect vsmd [from the shell]

2) show vsf session all brief | grep <source-ip> | grep >dest-ip> ---> Copy the session handle ID from this command. It would be a hex value in the beginning on the line.

3) show stream session handle detail <session-handle>

4) show idp event-stats [ There will a bunch of counters displayed.]

3) clear idp event-stats

[ Have the customer Initiate traffic from source to destination] 

4) show idp event-stats [ Please run this command multiple times throughout the test and note down which drop counters are incrementing ]
