-  1   | [CSIT-1782](https://jira.fd.io/browse/CSIT-1782) | Multicore AVF tests are failing when trying to create interface. Frequency is reduced by CSIT workaround, but occasional failures do still happen.

At least for max scale, in allotted time (limited by session 500s timeout) due to worse slow path performance than previously measured and calibrated for. CSIT removed the max scale NAT tests to avoid this issue.
-  3   | [CSIT-1802](https://jira.fd.io/browse/CSIT-1802) | All testbeds: AF-XDP - NDR tests failing from time to time on small loss.
-  4   | [CSIT-1845](https://jira.fd.io/browse/CSIT-1845) | AVF 9000B any ndrpdr test may start failing due to packets not arriving in one or both directions.
-  5   | [CSIT-1849](https://jira.fd.io/browse/CSIT-1849) | 2n-clx, 2n-icx: UDP 16m TPUT tests fail to create all sessions.

- 16   | [CSIT-1922](https://jira.fd.io/browse/CSIT-1922) | 2n-tx2: AF_XDP MRR failures. On other testbeds MRR regressions and PDR failures.
- 17   | [CSIT-1924](https://jira.fd.io/browse/CSIT-1924) | An l3fwd error in 200Ge2P1Cx7Veat-Mlx5 test with 9000B.
- 18   | [CSIT-1939](https://jira.fd.io/browse/CSIT-1939) | 3na-spr, 2n-zn2: VPP fails to start in first test cases.
