Hi Dave&community, I have added a fix as gerrit review id 37379. gerrit link: https://gerrit.fd.io/r/c/vpp/+/37379 <https://gerrit.fd.io/r/c/vpp/+/37379>
short description: "set policer classify interface loop1 ip4-table 0 del" may raise crash when worker threads handoff process ip4-policer-classify node. Especially under continuous flow test,if the delete of interface policer classify just occurs after node nat44-in2out-worker-handoff and before node ip4-policer-classify with handoff worker thread, the handoff worker thread will raise crash because of the pcm->classify_table_index_by_sw_if_index[ti][sw_if_index] has been invalid. Please have a look at my patch and review it. Thanks and Regards, Huawei LI
