ASA context1 with failover showing 99% memory used

Tshi M

One of my ASA is running multiple context (2) and failover "active/standby". One of the context is showing 99% memory used. How do I clear up of free up the memory?

Reboot would be the easist way :). If that is a possible in your particular environment?

Also have a look at this link:

Hi Farrukh,

I thought of rebooting but the reload option is not available. I would have to physically reboot the unit since it is at remote location.

Try to pin down the process that is utilizing most resources. Clear the xlate and arp tables.

In fact do a 'clear local-host all'

'clear xlate' 'clear arp' and see if it gets any better.

Both commands did not help. I went to the remote site and I physically rebooted the firewall but context (ctx) still showing 100% of memory used while context (admin) is showing 0%.
