Description (partial)

On a Cisco IOS device configured for DMVPN and IPSec, a leak in the "Chunk Manager" process may be observed.

In the output of 'show memory allocating-process totals' or 'show memory summary', this is seen to be due to to "SADB Peering Ch[unk]".

Over time, this may result in depletion of available memory on the device, and can also lead to crashes.

This is observed when DMVPN and crypto (IPSec) are configured. The leak occurs when a peer changes state from up to down.
