Print Page - EFW starting to work slow after certain time and kernel error

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:

Code:

Proc: i5@3.10 GHZ
Ram: 4 GB DDR3
Hdd: 1 TB
NICS: 2 x 1 GB cards

Endian info:

Code:

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:

Code:

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:

Code:

Pinging 10.213.0.1 with 32 bytes of data:
Reply from 10.213.0.1: bytes=32 time=<1ms TTL=64
Reply from 10.213.0.1: bytes=32 time=<1ms TTL=64
Reply from 10.213.0.1: bytes=32 time=<1ms TTL=64
Reply from 10.213.0.1: bytes=32 time=<1ms TTL=64

After

Code:

Pinging 10.213.0.1 with 32 bytes of data:

Reply from 10.213.0.1: bytes=32 time=61ms TTL=64
Reply from 10.213.0.1: bytes=32 time=59ms TTL=64

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.

Code:

System	2011-08-24 14:47:20	kernel [29027.210473] Disabling IRQ #16

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!!
