Sudden network loss within RHEL5 guest

Hi all

We have several RHEL 5.1 guests on our VI 3.5 platform. The ESX Hosts have 3.5 U1 installed. The RHEL 5.1 guests are 64Bit versions.

Once or twice a day the guests are not reachable any more. The interface within the guest is up, but it is not reachable any more. An arp or arp -a command shows us an empty table, even the local adapter does not show its own arp entry any more. After the restart of network service everything is ok again.

Does anyone know this issue?

I've seen a similiar problem with cloned RHEL guests and the problem was they were all bound to the same MAC address. May not be your issues, but you may want to check the MAC address binding for each of the guests...if they are all bound to the same MAC - when one is restarted other have a tendancy to drop off the network.

In the X GUI it is the last tab on the networking X Window - you can just uncheck the Bind to MAC XXX.XXX.XXX option.
