ARP problems, LAN interface timeouts

[check-ict]

I have a simple Zentyal installation with 2 network cards (virtual).

Eth0 is for WAN
Eth1 is for LAN

Sometimes the LAN interface has a short timeout period. I tracked the problem down to a ARP command:

for arptable in `arp | grep "eth1" | cut -d " " -f1`; do arp -d $arptable; done

This command deletes the arp entries on eth1. If I run this, all LAN access is normal again.

How can I stop these sudden timeout moments?

Can anyone help me with this?

Hi, I am facing the same problem: sometimes Zentyal cannot be reached. I do not have a solution, but I have made a complete and deep analysis that may lead to a solution. I've just replied a similar problem, check the following post: http://forum.zentyal.org/index.php/topic,8229.0.html

I know I am kind of late, but anyway I hope this can help...
