In the UNH IOL we see intermittent failures from the func_reentrancy_autotest which happen regardless of platform. Sometimes the report looks like: (from https://lab.dpdk.org/results/dashboard/patchsets/17321/) 27/93 DPDK:fast-tests / func_reentrancy_autotest FAIL 3.08s (exit status 255 or signal 127 SIGinvalid) --- command --- 07:03:58 DPDK_TEST='func_reentrancy_autotest' /home-local/jenkins-local/jenkins-agent/workspace/Arm-gigabyte-Unit-Test-DPDK/dpdk/build/app/test/dpdk-test -l 0-63 --file-prefix=func_reentrancy_autotest --- stdout --- RTE>>func_reentrancy_autotest Too many lcores, some cores will be disabled Func-ReEnt CASE 0: eal init once PASS Func-ReEnt CASE 1: ring create/lookup PASS Func-ReEnt CASE 2: mempool create/lookup FAIL Test Failed RTE>> Sometimes it looks like: --- command --- 12:35:49 DPDK_TEST='func_reentrancy_autotest' /home-local/jenkins-local/jenkins-agent/workspace/Generic-Unit-Test-DPDK/dpdk/build/app/test/dpdk-test -l 0-15 --file-prefix=func_reentrancy_autotest --- stdout --- RTE>>func_reentrancy_autotest --- stderr --- EAL: Detected 16 lcore(s) EAL: Detected 2 NUMA nodes EAL: Detected static linkage of DPDK EAL: Multi-process socket /var/run/dpdk/func_reentrancy_autotest/mp_socket EAL: Selected IOVA mode 'PA' EAL: No available 1048576 kB hugepages reported EAL: VFIO support initialized EAL: Invalid NUMA socket, default to 0 APP: HPET is not enabled, using TSC as default timer EAL: FATAL: already called initialization.
