Hello guys,
So...I just installed endian and I'm testing it for a relative small network (500 max clients), i'll start by showing some information about the machine.
Hardware:
Proc: i5@3.10 GHZ
Ram: 4 GB DDR3
Hdd: 1 TB
NICS: 2 x 1 GB cards
Endian info:
Appliance Community
Version 2.4.1
Kernel 2.6.32.25-57.e40.i586
Uptime 10h 19m
Data updated at 17:02:36
Network configuration:
Green: 10.213.0.1/23, eth0
Red: 10.210.0.213/24, eth1
Services started:
DHCP, firewall, IPS, traffic monitoring
The problem The problem is the following...after a certain time ( aprox 1 hour) EFW starts to work slow, the internet speed drops from 98 Mpbs to 4 Mpbs and the latencity increases very much.
Here is an example.
Before:

the ping starts at 99 ms and goes down to <1 then goes up again to 100 and counting down again...and so on till the end of time
If I reboot EFW it works fine for about and hour or so.... I have looked into the logs to see what could trigger this and I think the following thing is the problem.

This error seems to come from a setting or component in the server but I haven't managed to track the respective setting/component responsible yet.
So...anyone willing to trow an idea into this issue?
Thank you!!
