evo-aftmand process causing increase in memory utilization

On all Junos and Junos OS Evolved platforms, when MPLS (Multiprotocol Label Switching) statistics is configured without LSP (Label-Switched Path) configuration, the rpd process will crash and impact the routing protocols. This leads to traffic disruption due to the loss of routing information.

On all Junos and Junos Evolved platforms where multiple PCEs (Path Computation Element) are provisioned and connected to Junos PCC (Path Computation Client) and when all the PCEP (Path Computation Element Protocol) sessions are down, LSP (Label Switched Path) control will not be returned to the PCC. As a result, if existing EROs (Explicit Route Object) becomes invalid, new ERO will not be computed by PCC and there will be traffic loss.

Traffic loss due to incorrect route resolution and KRT queue getting stuck with 'EINVAL -- Bad parameter in request' error
Product-Group=evo
On all Junos and Junos OS Evolved platforms, due to a bug in route resolution over specific types of next hops, the route can resolve over itself and the nexthop chain keeps expanding. Due to this issue, the depth of recursion gets higher than supported and the KRT (Kernel Routing table) queue returns errors for nexthops. As a result, there will be incorrect route resolution, traffic loss and occasionally, the rpd (routing protocol deamon) crashes. The necessary configurations and conditions that will result in this issue are below 1. BGP (Border Gateway Protocol) Prefix-Independent Convergence (PIC) ("protect core") is configured and BGP receives same prefix from EBGP and IBGP neighbors 2. BGP LU (Labeled Unicast) with "protection" to create backup path to protect the active and BGP receives same prefix from EBGP and IBGP neighbors 3. Mutually recursive Route resolvability situations like Resolving using Default-route (not having proper resolution config)
