Hi here is an article explain how IPSO manages memory. Hope that helps Resolution 17810: Why does memory utilization stay high even if there's no load on the system?
Bookmark This Page Subject: Why does memory utilization stay high even if there's no load on the system? Product Line: IPSO (Operating System) Category: System Monitoring Version: Date Modified: 10/16/2005 Description: In Voyager, the memory utilization keeps increasing. It may continue to stay at high levels (90-95%) although the firewall is no longer under heavy load. Solution: This is a normal behaviour in UNIX-type systems such as IPSO. The operating system will hold data in memory until the memory is required for another purpose. At that time, the operating system will purge the parts of memory not currently in use and make it available for the appropriate purpose. Original Message: ----------------- From: Peter G.

We recently upgraded our 512MB IP350 from NG to NGX R61. In so doing, the memory utilization went through the roof, from a maximum of MAYbe 70% memory utilization to now NEVER being LESS than 95% memory utilization. We have pretty low traffic levels (typically less than 10% CPU utilization), and no more than three or four SecuRemote VPN users at a time, so I was shocked at the difference. My question: Given that we've maxed out the box (with 512MB) is the high memory utilization anything we should be concerned about? Or is the memory utilization we're seeing just attributable to memory caching? I'd hate to swap my IP350 out to an IP380 just to be able to load it with more memory...
