Cisco ASA: How to free memory without reboot?

Question

How can I free up some memory in our Cisco ASA 5510 without rebooting it? We urgently need to free memory otherwise it will crash, but we can't reboot it in the next 2 days.

Solution

First figure out what is eating up your memory

sh mem detail
sh proc detail

Something like this could bring the memory down but might not be what you desire. Also remember logging takes memory I belive.

Thanks! We deactivated some options and seems that the memory is decreasing very slowly (aprox 1% every 3 hours). We are hitting now 95% memory usage.
