Intermittent packet drop seen when running UDP mesh flow tests with 4096 flows per port in b2b topology #49

Open ashutshkumr opened 1 year ago

ashutshkumr commented 1 year ago

Describe the bug Tx and Rx count for some flows in the UDP header mesh flows test do not match towards the end of the test when 4096 flows are configured for each port in b2b.

To Reproduce

git clone https://github.com/open-traffic-generator/conformance.git
cd conformance && git checkout c2c306b

./do.sh topo new cpdp
./do.sh pregotest

OTG_ITERATIONS=2 ./do.sh gotest -tags="perf" -run "^TestUdpHeaderMeshFlowsPerf$"

Expected behavior The packet count for tx and rx should be equal for all flows.
