The old NS series needed an in-memory entry for each member of service and address groups for each policy. If you have a lot of groups and policies, this is why. There is no easy way to get the reason for it, for CLI there are some get memory commands, but they are very technically.

Have you got reasonably new firmware? Version 5.1 or greater?  I just looked at a NS5GT with a dozen policies, firmware V5.2, and memory usage is not high. On this particular NS, the users get their key via a command line setup and there is not a policy for each user.

6.2 uses better memory algorithms, so the memory usage should not be high. What is your understanding of "very high"? How much is  used in percents?

This shows the absolute  used/free figures.
get memory

You can try to extract more details out of

So you are showing more than half your memory free. That is my idea for usage as "not high". Your first post said usage was "very high". Does the output above reflect the same overall usage level as your first post? ... Thinkpads_User

15695840 / (27845984 [alloc] + 15695840 [free])  = 36% free. But that is more than enough.
