Recently deployed several PA-5250s Running 10.1.3 and there is a issue that randomly comes and goes.
Latency for traffic going through the firewalls spikes to 100-500ms. I was able to capture one thing that looked peculiar and that was flow_fpga_ingress_exception_err counts were high (8169388322) and the rate was high (12468). But I can't seem to find a good definition as what this would indicate.
I also caught the packet descriptor (on-chip) (average): with 100 across the first two rows.
I failed to capture the CPU Cores at the same time though.
You may be able to get more context looking at global counters: show counter global | match fpga
I would ask the same question as you currently are running the preferred/stable version of 10.1.
However, instead of questioning you, I hope they are providing a solution as you seem to already have a case with them.
I am curious to hear what their solution was, if they provide one.
