EAP 2 - Ram Utilisation

I have a similar problem with RAM on XG210v3@v18 EAP(0) to EAP2...

Wow, other than Big_Buck this is the first graph on an actual appliance with a production license and the memory usage is pretty high. i am guessing those drops are reboots when the orange graphs just fall off and then climb up all the way. Jaroslav Faldik can you tell us a little more about your setup as far as 

1. IPS

2 DPI or proxy in use for AV and categorization

3. How many users and firewall rules and if anything else you are using that maybe using the ram.

SaschaParis showed his appliance to be swapping heavily on 4GB ram, I wonder what the swap usage is on your appliance. Can you share a snapshot of "top" on console

Yes, those drops are reboots. Some of them are spontaneous reboots. Uptime is max. about 5-6 days...
So far we use a XG210 firewall under licence Basic firewall for SSL VPN (remote access - cca 30 users) and IPSec site-to-site (cca 30 tunnels). We have an active licence Network protection but we do not use it yet. I will try to transfer the existing configuration to another box with a clean installation of the v18 EAP2. Perhaps the problem is related to the upgrade from v17.5.8 MR8 to v18 EAP.

I had some spontaneous reboots on EAP1 but EAP2 is stable for me. It is a little concerning that it is rebooting all by itself. Clean install shouldn't matter as XG does a clean install and transfers your configuration to the new firmware but it won't hurt to test a clean install. Thanks for sharing your configuration.

Prism interesting ram changes with IPS enabled. Usually hyperscan only affects throughput. Interesting to see your ram usage drop also.

Hi folks,

today rebuilt my e3-1225 based system with a new BIOS. The memory usage was down as expected when first started, but I ran an IPv6 test that failed because  of MTU size, so I changed the MTU on two interfaces to 9000 (one internal and the WAN) and memory immediately grew to ver 70%. I restarted the XG because it wasn't behaving and now have MTU on all interfaces set at 9000 with memory at 73%.
