Hello,

I am facing a problem with the scheduler library DPDK 18.11.10 with 
default
scheduler settings (RED is off).
It seems like some of the pipes (last time it was 4 out of 600 pipes)
start incorrectly dropping most of the traffic after a couple of days of 
successful work.

So far I've checked that there are no mbuf leaks or any
other errors in my code and I am sure that traffic enters problematic 
pipes.
Also switching a traffic in the runtime to pipes of another port 
restores the traffic flow.

Ho do I approach debugging this issue?

I've added using rte_sched_queue_read_stats(), but it doesn't give
me counters that accumulate values (packet drops for example),
it gives me some kind of current values and after a couple of seconds
those values are reset to zero, so I can say nothing based on that API.

I would appreciate any ideas and help.
Thanks.
