High memory usage by objects of type cmp. Using SP-DAG and a small Large Scale NAT (LSN) pool, some TMMs may not have any local translation addresses. If connections are routed out a VLAN that has cmp-hash src-ip, a small amount of memory may be leaked.
A small amount of memory may be leaked. The aggressive sweeper might kill connections. TMM may crash. Traffic disrupted while tmm restarts.

Using the default DAG with small LSN Pools gives all TMMs local translation endpoints. To prevent the leak, allow only VLANs with cmp-hash dst-ip in the LSN pool egress interface list.
