Hi, I am facing a crash in the below code. It's 12 worker/1 core setup. we are using bit old VPP - 20.09.
function under suspect is --- buffer_send_to_node() * vlib_frame_t *frame; * u32 *to_next; * * frame = vlib_get_frame_to_node (vm, node_index); * frame->n_vectors = 1; * to_next = vlib_frame_vector_args (frame); * * to_next[0] = buffer_index; * * vlib_put_frame_to_node (vm, node_index, frame ); * return; The crash is seen at #3 <signal handler called> #4 vlib_frame_vector_byte_offset (scalar_size=<optimized out>) at /home/jenkins/vpp/build-root/install-vpp-native/vpp/include/vlib/node_funcs.h:259 #5 vlib_frame_vector_args (f=<optimized out>) at /home/jenkins/vpp/build-root/install-vpp-native/vpp/include/vlib/node_funcs.h:270 #6 buffer_send_to_node (vm=vm@entry=0x7fc406c323c0, node_index=332, buffer_index=buffer_index@entry=19753015) at /home/jenkins/test_buffer.c:1105 .. .. #11 0x00007fc43bfbd702 in dispatch_node (last_time_stamp=61944131704815156, frame=0x7fc40695c500, dispatch_state=VLIB_NODE_STATE_POLLING, type=VLIB_NODE_TYPE_INTERNAL, node=0x7fc4107c0480, vm=0x7fc406c323c0) at /home/jenkins/vpp/src/vlib/main.c:1197 #12 dispatch_pending_node (vm=vm@entry=0x7fc406c323c0, pending_frame_index=pending_frame_index@entry=4, last_time_stamp=61944131704815156) at /home/jenkins/vpp/src/vlib/main.c:1355 Can an allocated frame at line 4 be freed via dispatch_pending_node in any conditions ?
