EFW Support

I have a 2.5.2 server running on a ESXi 5.1 server.  I'm seeing this in the messages once or twice a day:

The box loses network connectivity for about 5 seconds when this happens.

Any ideas?  Not sure why I stick around with Endian, but I have 15 of these boxes around the country and it's been great to me.  Just wish it had better support from the community.

I've had a similar problem, in my case server hangs and I can only reboot. I tried Endian 2.5.2 and XenServer 6.2.0 with Endian, same thing. It was a ML110. When I changed bios feature about power management it was more stable but sometimes hangs again. So I've buyed new hardware.
