Might be defect CSCtb58989 (fixed in 8.2(2.3))

Symptom:

ASDM fails to load on ASA 8.2, due to no available DMA memory.

This issue occurs if logging is enabled along with crypto tunnels.

Conditions:

Logging is enabled.

Crypto (IPSec, SSL) is also enabled.

Workaround:

Downgrade ASA to 8.0.x or configure the logging queue to a value of 512. After

restoring the logging queue to default, need to reload the box to reclaim DMA

memory.

Hi Hamood,

Can you try all other ways of generating the keys.....

crypto key generate rsa modulus 2048 and few other ways to create the key.....

before that do crypto key zeroize rsa command and then do create the key
