map_guest_mem may be called from worker-thread/dataplane. It has a call
to vlib_log and may crash inside vlib_log's ASSERT statement
/* make sure we are running on the main thread to avoid use in dataplane
code, for dataplane logging consider use of event-logger */
ASSERT (vlib_get_thread_index () == 0);
The fix is to convert the vlib_log call in map_guest_map to event logger
