Description

Using 5.0.3

running AFPv3, 4.19 kernel, using cluster_qm, 2-3Gbps but huge amounts of unique http/dns flows (40k eps) :

      "spare_delta": -21,
      "memcap_delta": 0,
      "icmpv4_delta": 0,
      "udp_delta": 219,
      "tcp_delta": 364612,
      "memuse_delta": -15096144,

There are no memcap hits.

memuse may be a valid case as it cleans up.

Some total pkt counters had negative too. Trying to reproduce more precisely.

If memuse decreases the delta would show a negative value. This is expected behavior.

The pkt counters would be weird. Would be great to get more info on that. (possibly related to #2845)
