Hi Dave,
I have back-merged changes committed in VPP18.10 to 18.01.
Change details is as given below -
commit 0610039fd06c760924fb92d0fc7b4d3e0ffeb8e3
Author: Dave Barach <dbar...@cisco.com>
Date: Thu Jul 12 13:00:47 2018 -0400
Now we are facing a crash during init time , it looks to me if we fire
vppctl while VPP is coming is causing the below crash, It is not always
re-producible. Do you have any idea about this issue?
*Crashing at* (File *src/vlib/main.c)*
569 void
570 vlib_node_sync_stats (vlib_main_t * vm, vlib_node_t * n)
571 {
572 vlib_node_runtime_t *rt;
573
574 if (n->type == VLIB_NODE_TYPE_PROCESS)
575 {
576 /* Nothing to do for PROCESS nodes except in main thread */
577 if (vm != &vlib_global_main)
578 return;
579
580 vlib_process_t *p = vlib_get_process_from_node (vm, n);
581 n->stats_total.suspends += p->n_suspends;
582 p->n_suspends = 0;
583 rt = &p->node_runtime;
584 }
585 else
586 rt =
587 vec_elt_at_index (vm->node_main.nodes_by_type[n->type],
588 n->runtime_index);
589
590 vlib_node_runtime_sync_stats (vm, rt, 0, 0, 0);
591
592 /* Sync up runtime next frame vector counters with main node
structure. */
593 {
594 vlib_next_frame_t *nf;
595 uword i;
596 for (i = 0; i < rt->n_next_nodes; i++)
597 {
598 nf = vlib_node_runtime_get_next_frame (vm, rt, i);
* 599 vec_elt (n->n_vectors_by_next_node, i) += 600
nf->vectors_since_last_overflow;*
601 nf->vectors_since_last_overflow = 0;
602 }
603 }
604 }
Back Trace is as below -
