Crash occurs while a core is doing rte_acl_classify() for a packet when other core is trying to build the same filter context using rte_acl_build(). How to resolve this issue without using lock as lock affects the performance ? or Is there any other way using lock which will not affect the performance. ? Thanks, Mohanraj V
