Hi An drew, Myself modified the code to suit some requirement. The plain vpp acl module also crashes in similar situation. I am expecting the vpp should crash while trying to add more sessions. The system has 64 GB RAM and vpp was using 3.44% of the memory while crashing. So the system is not out of memory but its not configured to use the available memory.
The relevant crash bt is this #5 __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:50 #6 0x00007f2fba309859 in __GI_abort () at abort.c:79 #7 0x00007f2fba4e0bba in os_panic () at /root/code/vpp/src/vppinfra/unix-misc.c:221 #8 os_out_of_memory () at /root/code/vpp/src/vppinfra/unix-misc.c:221 #9 0x00007f2fba721701 in clib_mem_alloc_aligned_at_offset (os_out_of_memory_on_failure=1, align_offset=0, align=64, size=98368) at /root/code/vpp/src/vppinfra/mem.h:243 #10 clib_mem_alloc_aligned (align=64, size=98368) at /root/code/vpp/src/vppinfra/mem.h:263 #11 alloc_aligned_16_8 (nbytes=12288, h=0x7f2f79d59998 <acl_main+728>) at /root/code/vpp/src/vppinfra/bihash_template.c:77 #12 value_alloc_16_8 (h=0x7f2f79d59998 <acl_main+728>, log2_pages=<optimized out>) at /root/code/vpp/src/vppinfra/bihash_template.c:462 #13 0x00007f2fbabdaefd in split_and_rehash_16_8 (h=h@entry=0x7f2f79d59998 <acl_main+728>, old_values=old_values@entry=0x7f2faf1d9a00, old_log2_pages=old_log2_pages@entry=5, new_log2_pages=new_log2_pages@entry=7) at /root/code/vpp/src/vppinfra/bihash_template.c:581 #14 0x00007f2fbabdcbd0 in clib_bihash_add_del_inline_with_hash_16_8 (arg=0x0, is_stale_cb=0x0, is_add=1, hash=<optimized out>, add_v=0x7f19a6991b48, h=0x7f2f79d59998 <acl_main+728>) at /root/code/vpp/src/vppinfra/bihash_template.c:901 #15 clib_bihash_add_del_inline_16_8 (arg=0x0, is_stale_cb=0x0, is_add=1, add_v=0x7f19a6991b48, h=0x7f2f79d59998 <acl_main+728>) at /root/code/vpp/src/vppinfra/bihash_template.c:985 #16 clib_bihash_add_del_16_8 (h=h@entry=0x7f2f79d59998 <acl_main+728>, add_v=add_v@entry=0x7f19a6991b48, is_add=is_add@entry=1) at /root/code/vpp/src/vppinfra/bihash_template.c:992 #17 0x00007f2f798bc8b5 in acl_fa_add_session (current_policy_epoch=<optimized out>, p5tuple=0x7f2f7cd5bc58, now=7927760728493450, sw_if_index=<optimized out>, is_ip6=0, is_input=0, am=<optimized out>) at /root/code/vpp/src/plugins/acl/session_inlines.h:577 #18 acl_fa_inner_node_fn (reclassify_sessions=1, node_trace_on=0, with_stateful_datapath=1, is_l2_path=1, is_input=0, is_ip6=0, frame=0x7f2f8c5f6440, node=0x7f2f8d6de980, vm=0x7f2f8d6f3dc0) at /root/code/vpp/src/plugins/acl/dataplane_node.c:1137 #19 acl_fa_outer_node_fn (do_stateful_datapath=1, is_l2_path=1, is_input=0, is_ip6=0, frame=0x7f2f8c5f6440, node=0x7f2f8d6de980, vm=0x7f2f8d6f3dc0) at /root/code/vpp/src/plugins/acl/dataplane_node.c:1428 #20 acl_fa_node_fn (is_l2_path=1, is_input=0, is_ip6=0, frame=0x7f2f8c5f6440, node=0x7f2f8d6de980, vm=0x7f2f8d6f3dc0) at /root/code/vpp/src/plugins/acl/dataplane_node.c:1456 #21 acl_out_l2_ip4_node_fn_hsw (vm=0x7f2f8d6f3dc0, node=0x7f2f8d6de980, frame=0x7f2f8c5f6440) at /root/code/vpp/src/plugins/acl/dataplane_node.c:1569 #22 0x00007f2fba595fa6 in dispatch_node (last_time_stamp=<optimized out>, frame=0x7f2f8c5f6440, dispatch_state=VLIB_NODE_STATE_POLLING, type=VLIB_NODE_TYPE_INTERNAL, node=0x7f2f8d6de980, vm=0x7f2f8d6de980) at /root/code/vpp/src/vlib/main.c:1039 #23 dispatch_pending_node (vm=vm@entry=0x7f2f8d6f3dc0, pending_frame_index=pending_frame_index@entry=7, last_time_stamp=<optimized out>) at /root/code/vpp/src/vlib/main.c:1198 #24 0x00007f2fba5978ff in vlib_main_or_worker_loop (is_main=0, vm=0x7f2f8d6f3dc0) at /root/code/vpp/src/vlib/main.c:1662 #25 vlib_worker_loop (vm=vm@entry=0x7f2f8d6f3dc0) at /root/code/vpp/src/vlib/main.c:1796 #26 0x00007f2fba5c4bf8 in vlib_worker_thread_fn (arg=<optimized out>) at /root/code/vpp/src/vlib/threads.c:1872 #27 0x00007f2fba529cb0 in clib_calljmp () from /lib/x86_64-linux-gnu/libvppinfra.so.21.06 #28 0x00007f2f72896d10 in ??

() In the frame 18 before calling acl_fa_can_add_session, why acl_fa_can_add_session is not failing ? What Is best way to set configuration so that vpp able to use more RAM ? Thanks, Mahamuda
