Hi,I am using vpp version 18.01.01 and i am getting a crash in memif plugin. The scenario is that, the worker thread is processing traffic from memif and the main thread deleted the memif. Is there any corner scenario where in the worker can crash because of the memif getting deleted.The worker thread is crashing when it is trying to access the memif queue ring.Please let me know if this type of scenario can crash the worker thread.back trace: 0x0000000000022c21: signal_handler at /epc-scaled/epc3/services/epcu/common/prdp/src/datapath/vpp-plugins/build/../../../common/inc/bt.h:349 0x00007feedd30df20: ?? ??:0 0x000000000001c401: memif_device_input_inline at /root/bkn/xfe/datapath/vpp/src/build-data/../src/plugins/memif/node.c:275 (inlined by) memif_input_fn_avx2 at /root/bkn/xfe/datapath/vpp/src/build-data/../src/plugins/memif/node.c:481 0x0000000000035e68: dispatch_node at /root/bkn/xfe/datapath/vpp/src/build-data/../src/vlib/main.c:988 (inlined by) vlib_main_or_worker_loop at /root/bkn/xfe/datapath/vpp/src/build-data/../src/vlib/main.c:1506 (inlined by) vlib_main_loop at /root/bkn/xfe/datapath/vpp/src/build-data/../src/vlib/main.c:1628 (inlined by) vlib_main at /root/bkn/xfe/datapath/vpp/src/build-data/../src/vlib/main.c:1783 0x000000000006c396: unformat_free at /root/bkn/xfe/datapath/vpp/src/build-data/../src/vppinfra/format.h:163 (inlined by) thread0 at /root/bkn/xfe/datapath/vpp/src/build-data/../src/vlib/unix/main.c:568
