Description (partial)

When an ASA is configured with 'jumbo-frame reservation', the amount of DMA memory reserved for the platform is incorrect. Over time, the ASA may not have enough free DMA to perform certain functions such as terminating SSL/SSH connections, sending syslogs, etc.

The ASA must have 'jumbo-frame reservation' enabled at the time of boot.
