The reason is that the memory has not been released
source file:
src/vcl/vppcom.c
func:
vcl_handle_mq_event
code:
case SESSION_IO_EVT_RX:
case SESSION_IO_EVT_TX:
s = vcl_session_get (wrk, e->session_index);
if (!s || !vcl_session_is_open (s))
break;
vec_add1 (wrk->unhandled_evts_vector, *e);
break;
Modify as follows.
case SESSION_IO_EVT_RX:
case SESSION_IO_EVT_TX:
s = vcl_session_get (wrk, e->session_index);
if (!s || !vcl_session_is_open (s))
break;
vec_add1 (wrk->unhandled_evts_vector, *e);
u32 index = ~0;
vec_del1(wrk->unhandled_evts_vector, index);
break;
This way, there won't be any out of bounds errors reported
