Hi,

yesterday i have upgraded my live asa to new version asa845-k8.bin

i read that a lot of bugs were fixed and some improvements with per user acls (need this feature).

After upgrade (zero downtime - i have A/S environment) my CPU and Memory were down:

fw01# sh processes cpu-usage non-zero

Sergiu,

t_match_compile is related to ACL complication into a format easily processed by ASA's code.

Typically problems like this should be temporary, duing big change for example.

Open up a TAC case, I'm not aware of anything specific to this.

We will need to take profiler info and some more detailed ingfo about your setup.

Maybe try your confirguration out in the lab.

M.

not able to simulate as i move back to asa844-1-k8.bin IOS

i will try to another ASA environment that is not so heavily used
