Ok that's unusual. Never seen before. I suppose that happens with unmodified dpdk 1.7? I do run acl_autotest with at least 256M of huge-pages as ACL is quite memory consuming and, as I remember, requires at least 2X32M areas of contiguous hugepages. But in that case (not enough hugepages) it should just fail with something like: ACL: allocation of 25953152 bytes on socket -1 for ACL_acl_ctx failed Any other details, so I can try to reproduce it: arch you build/run it on? amount of free memory in the system? Wonder what pstack says? Thanks Konstantin
