Hello Everyone, I know 18.01 is not supported now , but just want to
understand what could be the reason for the below crash, we are adding
entries in pool using pool_get_alligned which is causing vec_resize. This
issue comes when reaches around 1M entries. Whether it is due to limited
memory or some memory corruption or something else? Core was generated
by `bin/vpp
-c co'.
Program terminated with signal 6, Aborted.
