VC disconnect from ESX server

We have a cluster with 2 ESX 3.01,32039 Servers (HP Proliant DL 580 G4, 8 CPus, 28 GB RAM, SAN Storage), and VIC.

When open a console, after some time (2h or 3h), one of this servers appears disconnect.

The Server is reachable using ping, ssh, ftp ..., I dont found any mistake or warning at link level (This Server are connect to Cisco 6509 1 Gb speed).

After execute "service mgmt-vmware restart" the system reconnect.

No Virtual Machines are sttoped.

Any sugestion?

I've have seen something like this before. The host disconnected while I was cloning 2 VM's at the same time (to a different host). I believe the service console is used to transfer data, so I think it may have disconnected during a period of high network activity over the service console interface.

Do you know what was happening in the ESX world when the your host disconnected?

Check for any potential IP address conflicts with your ESX host which is disconnecting.

To connect the vSwitch to the net we are attaching 2 ethernet cards into a EthernetChannel in a Cisco 6509 Switch (like a bonding connection).

The console is using other card with a 1Gb

I dont found any error via console (at Cisco Level)
