Description (partial)

Symptom:
Unable to successfully enable coredump when ASA high memory utilisation.

ciscoasa(config)# show mem
Free memory:        2789081984 bytes (43%)
Used memory:        3816718592 bytes (59%)
-------------     ------------------
Total memory:       6442450944 bytes (100%)

ciscoasa(config)# show coredump filesystem 

'disk0:' has no coredump filesystem

ciscoasa(config)#

On Manually trying to enable:

ciscoasa(config)# coredump enable filesystem disk0: size 10

WARNING: Enabling coredump on an ASA5585-SSP-10 platform will delay the reload of
the system by up to 30 minutes in the event of software forced reload.
The exact time depends on the size of the coredump generated.


Proceeding with resizing to 10 MB results in
deletion of current 100 MB coredump filesystem and
its contents on 'disk0:', proceed ? [confirm]
ciscoasa(config)# 

ciscoasa(config)# show coredump filesystem 

'disk0:' has no coredump filesystem
ciscoasa(config)# 
ciscoasa(config)# coredump enable filesystem disk0: size 20
