The IPS40 is showing missed packets yet the Inspection Load remains at 0.
1. What would cause Missed Packets and is there a "best" method to troubleshot the situation?
2. Why does the Inspection Load remain at 0?
vs0 is currently assigned to PortChannel0/0 (Backplane interface)

Importan to let you know that for missed packets the IPS count packets being dropped byL2errors and oversupscription.
Based on the load being on 0 I would say it would make sense to think about L2 errors, is there a way you could doble check the layer 2 connectivity between them.
The IPS and Firewall are connected through PortChannel0/0. Not sure how you can check L2 connectivity on a backplane connection. Any ideas?
What version are you running
Also share the following:
show stat virt
Also over the show tech look the following :
exec: cat /proc/net/cisco/cids-shared.info
And let me know the free buffer percentage you see there

On the show tech I do not see the missed packet percentage on 50 % or any other value than 0
Can you double check that please
Having just witnessed another indication form the Sensor Health gadget that packets were being missed, I again ran the commands you suggested with a result of 0 missed packets in the output. Is it possible the Sensor Health gadget is reporting false indications?
