what code is on the ASA?

Here are some possible causes and resolutions for high memory utilization:

Event logging: Event logging can consume large amounts of memory. In order to resolve this issue, install and log all events to an external server, such as a syslog server.

Memory Leakage: A known issue in the security appliance software can lead to high memory consumption. In order to resolve this issue, upgrade the security appliance software.

Debugging Enabled: Debugging can consume large amounts of memory. In order to resolve this issue, disable debugging with the undebug all command.

Blocking Ports: Blocking ports on the outside interface of a security appliance cause the security appliance to consume high amounts of memory to block the packets through the specified ports.In order to resolve this issue, block the offending traffic at the ISP end.

I am running 8.0(4)

I am logging to a syslog !

No deb is enabled.

I am blocking the ports on the outside interface and not at the ISP end.

Thx

Vlad,

i cant recommend a code version to you but if you have access to cisco site, check the software download link below for latest releases. The latest code is 8.2.1 i believe but i'm not sure how reliable that code is....
