ASA 5510 - Memory allocation Error

Hi all,

My customer is facing with the above error. He has done the following:

 

Primary ASA showed Memory allocation Errors in the logs, in fact saving config was not possible
after removing Basic Threat Detection config and adding it again saving configuration was possible again, but Memory allocation Error still appear in the logs.

customer then failover to secondary which is now active, and to my knowledge this is fine on the secondary -active

Hello, The problem doesn't

Hello,

 

The problem doesn't seem to be related with DRAM but with flash memory.

Can you run a 'show flash' and try 'fsck flash'

 

Also I can see you are running 8.2 and 256 MB RAM, be aware of recommended memory:
