Hi, Deterministic NAT preallocate vector with 1000 session slots for each host from inside network range, so it will take some time https://wiki.fd.io/view/VPP/NAT#Memory_requirements

First, I thought drop rate was for main heap memory locking, so I changed source code and comment mheap_maybe_lock and mheap_maybe_unlock on mheap_usage command, but when the main heap is busy I have drop rate for incoming traffic. :( Is it normal behavior Or it is performance problem for memory? Thanks!
