90D Memory

[bobm]

I think we' re finally going to upgrade our 60C with 512MB fixed RAM since I can barely use any features in 5.0 FW without memory use spiking. I have to reboot about every two weeks to get memory back under 70%. But before we spend money on a new box, I want to make sure we aren' t going to be in the same position again in six months. We currently have about 35-40 users with possibility of about 50. 2 WAN links load balancing and failover. Running a small handful of Web Filter policies. Can someone tell me the amount of memory in the 90D? Is it replaceable/upgradable? Have looked in data sheets, quick start guides, etc with no luck. Thanks

I' m experiencing high RAM usage and it seems that there is a lot of it (more than 1 GB) used by cached that seems not to be cleaned up.

I don' t think there is any CLI command to force release cache, but cache automate release once kernel need more memory for something else.

The best command for looking into high memory is " diag sys top-summary" It' s new for 5.0 but unlike ' diag sys top' it looks at shared memory, child process and open files.
