This read-only Counter tracks the number of unsuccessful attempts to allocate memory from the local management agent's heap. An administrator uses a rise here, distinct from ppePacketMemoryFailures, to isolate a problem specifically in the management agent rather than in packet forwarding. For example, the admin sees ppeMgtMemoryFailures increment while ppePacketMemoryFailures stays at zero, isolating the issue to the management agent rather than data-plane processing.
